This book was released on 2018-09-28 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the isolation and characterization of graphene, there has been a growing interest in 2D materials owing to their unique properties compared to their 3D counterparts. Recently, a family of 2D materials of early transition metal carbides and nitrides, labelled MXenes, has been discovered (Ti2CTz, Ti3C2Tz, Mo2TiC2Tz, Ti3CNTz, Ta4C3Tz, Ti4N3Tz among many others), where T stands for surface-terminating groups (O, OH, and F). MXenes are mostly produced by selectively etching A layers (where A stands for group A elements, mostly groups 13 and 14) from the MAX phases. The latter are a family of layered ternary carbides and/or nitrides and have a general formula of Mn+1AXn (n = 1-3), where M is a transition metal and X is carbon and/or nitrogen. The produced MXenes have a conductive carbide core and a non-conductive O-, OH- and/or F-terminated surface, which allows them to work as electrodes for energy storage applications, such as Li-ion batteries and supercapacitors. Prior to this work, MXenes were produced in the form of flakes of lateral dimension of about 1 to 2 microns; such dimensions and form are not suitable for electronic characterization and applications. I have synthesized various MXenes (Ti3C2Tz, Ti2CTz and Nb2CTz) as epitaxial thin films, a more suitable form for electronic and photonic applications. These films were produced by HF, NH4HF2 or LiF + HCl etching of magnetron sputtered epitaxial Ti3AlC2, Ti2AlC, and Nb2AlC thin films. For transport properties of the Ti-based MXenes, Ti2CTz and Ti3C2Tz, changing n from 1 to 2 resulted in an increase in conductivity but had no effect on the transport mechanism (i.e. both Ti3C2Tx and Ti2CTx were metallic). In order to examine whether the electronic properties of MXenes differ when going from a few layers to a single flake, similar to graphene, the electrical characterization of a single Ti3C2Tz flake with a lateral size of about 10 μm was performed. These measurements, the first for MXene, demonstrated its metallic nature, along with determining the nature of the charge carriers and their mobility. This indicates that Ti3C2Tz is inherently of 2D nature independent of the number of stacked layers, unlike graphene, where the electronic properties change based on the number of stacked layers. Changing the transition metal from Ti to Nb, viz. comparing Ti2CTz and Nb2CTz thin films, the electronic properties and electronic conduction mechanism differ. Ti2CTz showed metallic-like behavior (resistivity increases with increasing temperature) unlike Nb2CTz where the conduction occurs via variable range hopping mechanism (VRH) - where resistivity decreases with increasing temperature. Furthermore, these studies show the synthesis of pure Mo2CTz in the form of single flakes and freestanding films made by filtering Mo2CTz colloidal suspensions. Electronic characterization of free-standing films made from delaminated Mo2CTz flakes was investigated, showing that a VRH mechanism prevails at low temperatures (7 to ≈ 60 K). Upon vacuum annealing, the room temperature, RT, conductivity of Mo2CTx increased by two orders of magnitude. The conduction mechanism was concluded to be VRH most likely dominated by hopping within each flake. Other Mo-based MXenes, Mo2TiC2Tz and Mo2Ti2C3Tz, showed VRH mechanism at low temperature. However, at higher temperatures up to RT, the transport mechanism was not clearly understood. Therefore, a part of this thesis was dedicated to further investigating the transport properties of Mo-based MXenes. This includes Mo2CTz, out-of-plane ordered Mo2TiC2Tz and Mo2Ti2C3Tz, and vacancy ordered Mo1.33CTz. Magneto-transport of free-standing thin films of the Mo-based MXenes were studied, showing that all Mo-based MXenes have two transport regimes: a VRH mechanism at lower temperatures and a thermally activated process at higher temperatures. All Mo-based MXenes except Mo1.33CTz show that the electrical transport is dominated by inter-flake transfer. As for Mo1.33CTz, the primary electrical transport mechanism is more likely to be intra-flake. The synthesis of vacancy ordered MXenes (Mo1.33CTz and W1.33CTz) raised the question of possible introduction of vacancies in all MXenes. Vacancy ordered MXenes are produced by selective etching of Al and (Sc or Y) atoms from the parent 3D MAX phases, such as (Mo2/3Sc1/3)2AlC, with in-plane chemical ordering of Mo and Sc. However, not all quaternary parent MAX phases form the in-plane chemical ordering of the two M metals; thus the synthesis of the vacancy-ordered MXenes is restricted to a very limited number of MAX phases. I present a new method to obtain MXene flakes with disordered vacancies that may be generalized to all quaternary MAX phases. As proof of concept, I chose Nb-C MXene, as this 2D material has shown promise in several applications, including energy storage, photothermal cell ablation and photocatalysts for hydrogen evolution. Starting from synthetizing (Nb2/3Sc1/3)2AlC quaternary solid solution and etching both the Sc and Al atoms resulted in Nb1.33C material with a large number of vacancies and vacancy clusters. This method may be applicable to other quaternary or higher MAX phases wherein one of the transition metals is more reactive than the other, and it could be of vital importance in applications such as catalysis and energy storage.

Book excerpt: 2D transition metal dichalcogenides (TMDs) and their heterostructures have shown great potential for next-generation device applications due to their unique and versatile electronic, optical and chemical properties. However, to exploit their potential in applications, it is crucial to establish reliable and reproducible synthesis methods for these atomically thin materials. In addition, efficient strategies for their synthesis with tailored properties must be developed. This work focuses on developing chemical vapor deposition (CVD) growth techniques for a range of TMD monolayers and their heterostructures, understanding the underlying growth mechanism, investigating their structure-property relationships, and exploring their functional applications. The work starts with the development of MoSe2-WSe2 lateral heterostructures, demonstrating the formation of high-quality atomically sharp p-n junctions. The synthesis of Janus SeMoS TMDs, with their unique asymmetric atomic configurations, presents the emergence of novel optical phenomena such as valley Zeeman splitting. The work also innovates in the direct growth of TMD monolayers on curved photonic structures, expanding the potential for photonic applications. In addition, a novel area selective growth technique using micromolding in capillaries (MIMIC) is introduced, leading to high-quality TMD patterns for advanced electronic and optoelectronic devices.

Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the current status of theoretical and experimental progress in 2 dimensional graphene-like monolayers and few-layers of transition metal dichalcogenides (TMDCs). Semiconducting monolayer TMDCs, due to the presence of a direct gap, significantly extend the potential of low-dimensional nanomaterials for applications in nanoelectronics and nano-optoelectronics as well as flexible nano-electronics with unprecedented possibilities to control the gap by external stimuli. Strong quantum confinement results in extremely high exciton binding energies which forms an interesting platform for both fundamental studies and device applications. Breaking of spatial inversion symmetry in monolayers results in strong spin-valley coupling potentially leading to their use in valleytronics. Starting with the basic chemistry of transition metals, the reader is introduced to the rich field of transition metal dichalcogenides. After a chapter on three dimensional crystals and a description of top-down and bottom-up fabrication methods of few-layer and single layer structures, the fascinating world of two-dimensional TMDCs structures is presented with their unique atomic, electronic, and magnetic properties. The book covers in detail particular features associated with decreased dimensionality such as stability and phase-transitions in monolayers, the appearance of a direct gap, large binding energy of 2D excitons and trions and their dynamics, Raman scattering associated with decreased dimensionality, extraordinarily strong light-matter interaction, layer-dependent photoluminescence properties, new physics associated with the destruction of the spatial inversion symmetry of the bulk phase, spin-orbit and spin-valley couplings. The book concludes with chapters on engineered heterostructures and device applications such as a monolayer MoS2 transistor. Considering the explosive interest in physics and applications of two-dimensional materials, this book is a valuable source of information for material scientists and engineers working in the field as well as for the graduate students majoring in materials science.

This book was released on 2024 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two-dimensional transition metal dichalcogenides (2D TMDs) have remained at the forefront of materials science research ever since their initial discovery over 15 years ago. Similar to graphene, 2D TMDs can be thinned down to atomic thicknesses while maintaining a clean surface free of dangling bonds. A crucial distinction from graphene is that 2D TMDs are semiconductors with band gaps that vary depending on their thickness. In addition, 2D TMDs offer other coveted characteristics, including short channel effect immunity, robust excitonic effects, and strong spin orbit coupling, making them promising for diverse applications such as ultra-scaled electronics, photonics, spintronics, flexible electronics, and biosensors. Despite extensive research and successful laboratory demonstrations showcasing the potential of 2D TMDs, the absence of commercial TMD-based products indicates that these materials are still in a developmental phase, with key challenges that need to be addressed. Since the initial mechanical exfoliation experiments used to isolate thin TMD flakes, a considerable amount of research effort has gone into realizing industrially-adaptive, scalable synthesis methods for large-area TMD films. Vapor-phase synthesis methods have made impressive progress in improving the grain size and orientation of 2D TMD films at the wafer scale. However, the absence of scalable methods for controlling defect density impedes the use of TMDs in various applications. The two-dimensional nature of TMDs make their properties particularly susceptible to crystalline defects, therefore it is crucial to understand how they are formed during synthesis and ultimately develop methods for controlling their density over large areas. Another bottleneck to 2D TMD manufacturing is the realization of doping strategies that are precise, uniform, and stable over time. Lastly, the majority of the large scale synthesis efforts focus on monolayer samples, overlooking the importance of developing growth methods for few-layer TMD films with uniform layer number control. This dissertation demonstrates approaches to control defects, dopants, and layering in the synthesis of 2D TMDs. The thesis first discusses the engineering of chalcogen vacancies in MoS2 films synthesized through metal organic chemical vapor deposition (MOCVD), achieved via post-growth annealing in controlled environments, and its effects on photophysics. Then, it delves into essential considerations about how modifications to the surface of sapphire substrates during the growth process impact the optical and electronic properties of MoS2 epilayers. Having established the synthesis of high-quality MoS2 films and native defect control, the thesis will shift to n-type doping by controlled atomic substitution of Rhenium (Re) down to ppm levels. Introducing Re dopants during the growth process is revealed to suppress chalcogen vacancy formation, leading to MoS2 films with enhanced crystallinity and transport properties. The breakthroughs discussed in this work pave the way for further exploration of dopant-defect interactions in substitutionally doped 2D semiconductors, and how they can be leveraged to improve material quality and the performance of (opto-)electronic devices. Addressing thickness control, the thesis presents a novel interrupted MOCVD growth approach for layer-by-layer epitaxy of MoS2 films with uniform layer number over large areas. Building upon the key findings presented in the thesis, the final chapter presents potential future research avenues like magnetic doping in 2D semiconductors and the deterministic growth and doping of heterodimensional TMDs.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transition metal dichalcogenides (TMDs), possessing a multitude of interesting properties, have emerged as an interesting choice for various types of electronic, optoelectronic and beyond CMOS device applications. Chemical vapor deposition (CVD) has been used extensively as an efficient, fast, reliable, and scalable route to grow uniform, high quality, large area TMDs. In this work, we report atmospheric pressure CVD (APCVD) and metal-organic CVD (MOCVD) growth of TMDs and study the effects of growth temperature, metal/chalcogen flux, reaction environment, etc. in modulating the shape, size, crystal structure, and uniformity of the grown film. To control the morphology more efficiently, we established a process for transition from compact two-dimensional (2D) domain to branched domain morphologies by varying the growth temperature and transition metal flux. Two different types of branched domains, fractals and dendrites, are observed which follow different growth mechanisms. In addition to the experimental investigations, we used a phase field simulation method for a better understanding of the dependence of the domain morphologies on the growth parameters. To control the 2D/3D growth mode, crucial role of chalcogen flux is investigated. While multilayer islands form in a chalcogen-deficient condition, a chalcogen-rich condition promotes lateral growth by restricting transition metal-rich nuclei formation. Study of APCVD growth with different carrier gases show that a reducing environment under hydrogen gas is more favorable to achieve uniform 2D growth. Based on the experimental observations, we propose an optimized CVD growth condition to achieve large-area high quality 2D TMD domains. Beside the APCVD growth of TMDs, an alternative approach via MOCVD growth under low pressure followed by a high-temperature sulfurization process under atmospheric pressure has also been explored. This two-step process can substantially heal chalcogen vacancies, suppress carbon/oxygen contamination, and produce more homogeneously distributed triangular monolayer domains with the electrical performance comparable to APCVD-grown domains

Available in PDF, EPUB and Kindle. Book excerpt: Highly photosensitive, tunable direct band gap materials of subnanometer thickness represent an important path forward in minimization of opto-electronic devices. It is inevitable that the scale of devices will soon move beyond the 2 nm node. With the ever decreasing scale of devices, two dimensional transition metal dichalcogenides (TMDs) offer a promising avenue towards reduced dimensionality and unveil novel direct-indirect band gap shift tuning capabilities by means of thickness, and composition. A primary goal of this work is to investigate bottom-up approaches to fabrication of integrated materials systems using chemical vapor deposition (CVD) grown TMDs. In that vein, this thesis presented examines the methods for growth of the transition metal dichalcogenide materials on a variety of metal oxide terminated substrates, graphene and directly onto an economical photocathode for the hydrogen evolution reaction in water splitting. Where the limits of CVD process preclude bottom-up fabrication, the research presents methods to vertically stack CVD-grown two dimensional materials and deposit them on arbitrary substrates via physical transfer techniques allowing for a single step process to obtain CVD grown TMDs on flexible substrates. Executing physical transfer allows us to reach the final goal of this work, to investigate a third type of optical tuning, that of uniaxial mechanical strain. The thesis probes a mechanical strain induced shift in the optical behavior of the MX2 (M=Mo, W; X=S, Se) materials.

Abstract: An atomically thin film of semiconducting transition metal dichalcogenides (TMDCs) is emerging as a class of key materials in chemistry and physics due to their remarkable chemical and electronic properties. The TMDCs are layered materials with weak out-of-plane van der Waals (vdW) interaction and strong in-plane covalent bonding enabling scalable exfoliation into two-dimensional (2D) layers of atomic thickness. The growth techniques to prepare these 2D TMDC materials in high yield and large scale with high crystallinity have attracted intensive attention recently because of the new properties and potentials in nano-elctronic, optoelectronic, spintronic and valleytronic applications. In this thesis, I develop methods for the chemical synthesis of 2D TMDCs films. The relevant growth mechanism and material characteristics of these films are also investigated. Molybdenum disulfide (MoS2) is synthesized by using molybdenum trioxide (MoO3) and sulfur (S) powder as the precursor. The films are formed on substrate pre-treated with reduced graphene oxide as the catalyst. However, this method cannot be extended to other TMDC materials such as molybdenum diselenide (MoSe2) and tungsten diselenide (WSe2) because reduced graphene oxide (rGO) reacts with selenium to form alloy materials rather than TMDC films. At the same time, the conversion of MoO3 to MoSe2 or that of tungsten trioxide (WO3) to WSe2 without the assistance of hydrogen in the chemical reaction is not thermodynamically feasible because the oxygen in the metal oxide cannot be replaced by selenium due to lower reactivity of the latter. On the other hand, I demonstrate that MoSe2 film can be synthesized directly by using MoSe2 and Se powder. Furthermore, the method of sulfurization or selenization of pre-deposited metal film can be promising due to precise thickness/size controls. Finally, some perspectives on the engineering challenges and fabrication methods of this family of materials will be given. Subjects: Transition metal compounds - Synthesis Chalcogenides - Synthesis

Available in PDF, EPUB and Kindle. Book excerpt: Abstract : The rapid development of two-dimensional (2D) materials has led to tremendous interest in the study of graphene and a series of mono- and few-layered transition metal dichalcogenides (TMDCs). One major attraction of TMDCs is their semiconducting nature with indirect to direct bandgap transition, when thinned from bulk to few- and mono- layers. Molybdenum disulfide (MoS2) is one of the 2D TMDCs that has gained increasing attention due to its promising optical, electronic, and optoelectronic properties. In this thesis, I will discuss my research on the synthesis of 2D MoS2 and the characterization of its optical properties by Raman, Photoluminescence (PL) and UV-Vis spectroscopy. Next, the application of 2D TMDCs for FETs and solar cells will be reviewed. Finally, my extended work on the oxide form (transition metal oxides) and zero-dimensional (0D) form of TMDCs will be discussed. Efficient solar cells constructed by MoO3 and other oxides, and the future application of 0D TMDCs will also be evaluated.

This book was released on 2017 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in two-dimensional (2D) electronic materials has exploded in the past decade, starting with the isolation of single layer graphene in 2004 by Novoselov. Similar to graphene, as a stable material in the single-layer, transition metal dichalcogenides (TMDs) further the advancement of 2D materials, but also provide an intrinsic transition to a direct bandgap in the single layer, thus giving these materials an advantage over graphene. Furthermore, TMDs have some of the highest notable Ion/Ioff ratios of other 2D materials, making them extremely favorable. However, none of these 2D materials can be used as a standalone for modern electronic applications, therefore, heterostructures of these materials must be created. An understanding of the way these materials are synthesized and ways to manipulate the synthesis is necessary to achieve such structures. Chemical vapor deposition (CVD) is a commonly used method to create single-layer TMDs among others such as mechanical exfoliation and metal sulfurization/selenization. Here I present facile methods by which to synthesize pristine, pure, 2D TMDs via CVD process manipulation. Additionally, in-situ operation of the CVD furnaces leads to the ability to alloy these materials and create heterostructures, leading to a study of tunable optical and physical properties. Last, I show the use of various/nanofabricated features on growth substrates in order to lead to a deeper understanding of the growth mechanisms for TMDs.
