These heterostructures capable of emitting multiple colors with high spectral purity are attractive platforms to explore new properties and physics in 2D materials. They also show promise for building versatile photonic devices that are easily solution-processed. The following appendices provide complementary information to the accomplished work presented in the main chapters. Specifically, Appendix A-H provide additional figures and tables to Chapters 2-9, respectively. Appendix I describes electrically driven light emission from 1D NWs and 2D nanoplates of cesium lead halide perovskites The remarkable solar performance of lead halide perovskites has been attributed to their advantageous physical properties that present many mysteries, challenges, as well as opportunities. The body of thesis here has demonstrated better control over the crystal growth and rational design of nanostructures of these fascinating materials, as well as better understanding of their complex solid-state chemistry can further enhance their applications.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal halide perovskites materials have gained significant research attention in the past decades as promising optoelectronic and photovoltaic materials, because of their inherently high photoluminescence quantum yield, long carrier diffusion length, high absorption coefficient, great defect tolerance and solution processibility. The emerging two-dimensional (2D) Ruddlesden-Popper (RP) phase halide perovskites inherit the desirable properties of 3D perovskites with improved environmental stability. To further improve the performance and realize extended functionalities of halide perovskite-based devices, it is of interest to explore the synthesis, fabrication, and stabilization of halide perovskite heterostructures as well as its integration with other materials, which have been challenging due to the labile nature of the materials. Particularly, the unique modular structure of 2D RP perovskites endows great tunability of the optical and electronic properties. Interfacing the diverse 2D RP perovskite with other 2D materials including graphene and transitional metal dichalcogenides (TMDs) through van der Waals (vdW) stacking potentially offers unlimited heterostructure configurations for exploration of novel physic in semiconductor heterostructures and design of high-performance applications. In this thesis, we review the progress of the above-mentioned topics, and discuss the challenges remaining and future promising directions in this field.

This book was released on 2019 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: All-inorganic perovskites have attracted tremendous interest for their tunable optical properties and remarkable stability when compared with its hybrid counterpart. Although considerable efforts have been devoted to synthesizing micro-crystalline domains and various nanostructures, it remains a considerable challenge to produce high-quality monocrystalline thin films that are indispensable for functional electronics and optoelectronics. Furthermore, due to the fragility of metal halide perovskites, it remains a standing challenge to use conventional lithography to create reliable electrical contacts, rendering the intrinsic electrical transport properties of such perovskite materials are often seriously convoluted/plagued by poor electrical contacts. Starting from the vapor phase deposition of cesium lead halide CsPbX3 (X=Cl, Br, I) microplates, we demonstrated the growth of large-area monocrystalline all-inorganic perovskite thin films on muscovite mica. We show highly oriented CsPbBr3 square microplates can be readily grown on the (001) surface of muscovite with an epitaxial relationship of CsPbBr3-(001) paralleled to muscovite-(001), CsPbBr3-[100] paralleled to muscovite-[100] and CsPbBr3-[010] paralleled to muscovite-[010], which eventually merge together to form a continuous monocrystalline thin film. Time resolved photoluminescence (TRPL) decay measurements give a carrier lifetime of 170 ns, considerably longer than that in spin-coated thin films and well comparable to that in the highest quality bulk crystals. Aiming to resolve the problem of poor electrical contacts, we have further developed a simple physical transfer approach to create high-quality van der Waals (vdW) contacts, where the prefabricated thin film gold electrodes are directly laminated onto the perovskite thin films with minimum interfacial damage to produce electrical contacts for functional devices. The electrical and photoelectrical transport studies demonstrated an extraordinary photocurrent gain exceeding 106. The van der Waals contacts enable not only accurate measurements at room temperature but also the exploration of electrical properties at cryogenic conditions. A record-high carrier mobility exceeding 2,000 cm2/Vs has been achieved at 80 K and a quantum interference induced weak localization behavior in halide perovskite materials with a coherence length up to 49 nm has also been revealed for the first time by magnetotransport studies at 3.5 K. The growth of large-area high-quality perovskite thin films and the integration of the damage-free metal integration approach mark important steps for both the fundamental investigation and potential applications of the perovskite materials in integrated optoelectronics.

Available in PDF, EPUB and Kindle. Book excerpt: Here, a new chapter in the long and distinguished history of perovskites is being written with the breakthrough success of metal halide perovskites (MHPs) as solution-processed photovoltaic (PV) absorbers. The current surge in MHP research has largely arisen out of their rapid progress in PV devices; however, these materials are potentially suitable for a diverse array of optoelectronic applications. Like oxide perovskites, MHPs have ABX3 stoichiometry, where A and B are cations and X is a halide anion. Here, the underlying physical and photophysical properties of inorganic (A = inorganic) and hybrid organic-inorganic (A = organic) MHPs are reviewed with an eye toward their potential application in emerging optoelectronic technologies. Significant attention is given to the prototypical compound methylammonium lead iodide (CH3NH3PbI3) due to the preponderance of experimental and theoretical studies surrounding this material. We also discuss other salient MHP systems, including 2- dimensional compounds, where relevant. More specifically, this review is a critical account of the interrelation between MHP electronic structure, absorption, emission, carrier dynamics and transport, and other relevant photophysical processes that have propelled these materials to the forefront of modern optoelectronics research.

Book excerpt: This book can be roughly divided into three parts: fundamental physico-chemical and physical principles of Nanoscience, chemistry and synthesis of nanoparticles, and techniques to study nanoparticles. The first chapter is concerned with the origin of the size dependence of the properties of nanomaterials, explaining it in terms of two fundamental nanoscale effects. This chapter also serves as a general introduction to the book, briefly addressing the definition and classification of nanomaterials and the techniques used to fabricate and study them. Chapter 2 lays out the theoretical framework within which to understand size effects on the properties of semiconductor nanocrystals, with particular emphasis on the quantum confinement effect. The optical properties of metal nanoparticles and metal nanostructures (periodic lattices) are discussed in Chapter 3. Chapter 4 is devoted to nanoporous materials, treating in detail their synthesis, structure and functional properties, as well as the physical properties of liquids confined in nanopores. The preparation methods, characterization techniques, and applications of supported nanoparticles are covered in Chapter 5. The sixth Chapter presents the essential physical-chemical concepts needed to understand the preparation of colloidal inorganic nanoparticles, and the remarkable degree of control that has been achieved over their composition, size, shape and surface. The last four Chapters are dedicated to a few selected characterization techniques that are very valuable tools to study nanoparticles. Chapter 7 concentrates on electron microscopy techniques, while Chapter 8 focuses on scanning probe microscopy and spectroscopy. Electron paramagnetic resonance (EPR) based spectroscopic techniques and their application to nanoparticles are explored in Chapter 9. Finally, Chapter 10 shows how solution Nuclear Magnetic Resonance (NMR) spectroscopic techniques can be used to unravel the surface chemistry of colloidal nanoparticles.
