This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapid development in Semiconductor research has brought excitement and challenges. New materials have pushed both academic and industry progress forward at a fast pace. Since the discovery of one-atomic layer of graphene in 2004, tremendous efforts have been devoted to pushing its properties to meet the technology demands, establish metrics and help accomplish milestones. The family of two-dimensional materials continue to expand. Transition metal dichalcogenides (TMDs) help compensate for the zero-bandgap of graphene and greatly increase the opportunities for their applications in electronics, optoelectronics, bioelectronics and medical-related applications. To enable electronic chips with higher density and faster processing/switching speeds and address technology bottlenecks, new correlated or functionalized two-dimensional materials are being positioned under the research spotlight. As one example, 1T phase tantalum disulfide (1T-TaS2) has presented a Mott state at around 180K, at which an abrupt change in its resistivity occurs. This unique property could help achieve two-dimensional Landau switch and realize ultra-low power, collective-state devices. However, large-scale synthesis of single crystalline monolayer of two-dimensional materials is still at its infancy. Fundamental questions as to the structural-property relationships of new materials or heterostructures await to be addressed. This dissertation focuses on the synthesis and characterizations of functional two-dimensional nanomaterials for beyond complementary metal oxide semiconductor industry. This dissertation starts with introducing the state of art of semiconductor industries and the progress of two-dimensional transition metal dichalcogenides (Chapter 1). It then addresses the two-dimensional materials synthesis methods and related characterization techniques (Chapter 2). Precursor selections and precursor-substrate interactions are discussed in Chapter 3. Then two specific nanomaterials are specially addressed in the next three chapters. Chapter 4 includes dissertation research work on synthesizing and characterization of pristine 1T-TaS2 while chapter 5 focus its functionalization and address the potential application and challenges. Chapter 6 is concentrated on 2H-MoS2 and evaluate its potentials in copper diffusion barriers. Chapter 7 provides a summary for all my research work and concludes this dissertation.

This book was released on 2012-12-06 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains papers presented at the NATO Advanced Research Workshop (ARW) Dynamic Interactions in Quantum Dot Systems held at Hotel Atrium in Puszczykowo, near Poznan, Poland, May 16-19,2002. The term low-dimensional systems, which is used in the title of this volume, refers to those systems which contain at least one dimension that is intermediate between those characteristic ofatoms/molecules and those ofthe bulk material. Depending on how many dimensions lay within this range, we generally speak of quantum wells, quantum wires, and quantum dots. As such an intermediate state, some properties of low-dimensional systems are very different to those of their molecular and bulk counterparts. These properties generally include optical, electronic, and magnetic properties, and all these are partially covered in this book. The main goal of the workshop was to discuss the actual state of the art in the broad area ofnanotechnology. The initial focus was on the innovative synthesis of nanomaterials and their properties such as: quantum size effects, superparamagnetism, or field emission. These topics lead us into the various field based interactions including plasmon- magnetic spin- and exciton coupling. The newer, more sophisticated methods for characterization of nanomaterials were discussed, as well as the methods for possible industrial applications. In general, chemists and physicists, as well as experts on both theory and experiments on nanosized regime structures were brought together, to discuss the general phenomena underlying their fields ofinterest from different points ofview.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanomaterials have attracted extensive interest due to their unique structure and excellent properties compared with their bulk counterparts. To obtain nanodevices with controlled properties, it is prerequisite to synthesize nanostructured materials with designed architecture. In this work, low (one- and two- ) dimensional nanomaterials with controlled structures have been synthesized and characterized based on chemical vapour deposition strategy. Our research targets cover one-dimensinoal hollow, solid, and solid @ hollow heterostructural nanomaterials including carbon nanotubes (CNTs), nitrogen-doped carbon nanotubes (NCNTs), SnO2 nanowires, Mo doped-SnO2 nanowires, Sn nanowires encapsulated in CNTs (Sn@CNTs), and two-dimensional Mo2S3 nanopetals. Dependence of product morphology, composition and phase structure on the synthesis conditions has been systematically investigated by changing temperature, growth time, gas flow, external atom doping, catalyst and employed substrate, to get insight into the correlation between the structure control and growth conditions of the products and their growth mechanism as well. High quality CNTs and NCNTs with uniform size were synthesized on carbon paper and Si wafer by introducing thin iron sputtering film as catalyst. High nitrogen content up to 10.4 at% was reached in the NCNTs. Controlled growth of SnO2 and Mo-doped SnO2 nanowires was obtained on different substrates including carbon paper, stainless steel and Cu to meet substrate requirements for practical applications. It was found that Mo doping could significantly improve the corrosion resistance of the SnO2 nanowires. Core-shell heterostructures of Sn nanowires @ CNTs were produced on carbon microfibers, stainless steel and Cu substrates. Rational control on the thickness and nature of the carbon shell of the heterostructures on carbon microfibers was realized by modulating growth parameters and introducing extra catalyst. Multi-generation Sn@CNTs were obtained by exploring SnO and SnO2 as starting materials. On the metallic substrates, Sn-alloy@CNT nanostructures were obtained. In another way, SnCo alloy nanowires @ CNTs with readily controlled Co content were achieved by introducing cobalt-contained precursor. Non-catalytic and catalytic growth of two-dimensional Mo2S3 nanopetals was investigated on carbon microfibers. Without catalyst, the nanopetals with high density were only obtained in a narrow range of the precursor concentration. With Au catalyst, uniform nanopetals with steady high density could be achieved in a wide range of the precursor concentration. Morphology, composition and phase structure of the nanostructures were characterized and analyzed by electron microscopy, X-ray diffraction, energy-dispersed spectroscopy and Raman spectroscopy.

Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, I explore simple chemical means to produce various nanomaterials. In Chapter 2, the synthesis of size-tuned bismuth telluride nanoparticles is discussed. The solution phase synthesis of bismuth telluride nanoparticles has been accomplished in the presence of a library of thiols as the capping ligand. These crystalline nanostructures range in size from?20 to?100nm with a relatively narrow size dispersity. Size and shape of the resulting nanostructures has been investigated as a function of chain length of the thiol and temperature. An investigation into the thermoelectric properties of the nanostructures shows promising electrical conductivity, thermopower, and thermal conductivity for undoped bismuth telluride. In Chapter 3, a soluble precursor for antimony telluride is described. This precursor was used to fabricate semiconductor nanowires of varying diameter and thin films through simple templatingmethods. Electrical conductivity and thermoelectric power measurements of these films are only slightly lower than for antimony telluride films fabricated by vacuum deposition. In Chapter 4, the polytetrafluoroethylene (PTFE)/metal nanocomposites are discussed. Palladium and nickel PTFE nanocomposites were made by impregnation of the polymer with metal acetates. Annealing and jet blowing of these materials form PTFE nanofiber/metal nanoparticle composites.
