This book was released on 2018 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two-dimensional (2D) materials have attracted tremendous research interest, as they offer novel physics, facile visualization by electron and scanning probe microscopy, and the potential to become next-generation electronic materials, all due to reduced dimensionality. Large-area 2D single crystals are needed for both fundamental scientific experiments and electronic device applications. New methods need to be developed to exploit state-of-the-art microscopy in the scientific investigation of 2D materials. Mechanisms behind the behavior of 2D-material based devices need to be resolved and new device concepts and applications need to be explored. This dissertation addresses these three aspects of 2D materials research. Using chemical vapor deposition growth of graphene on copper as a platform, the first part of my research in this thesis demonstrates a facile method involving a simple in-situ treatment of the copper catalytic substrate right before the growth that results in mm-sized graphene single crystals, elucidating the key factors of achieving large-area 2D single crystals. The second part of this work developed experimental methods to resolve important issues in 2D materials research by employing modern transmission electron microscopy. Here, a method has been developed to determine the edge orientation and termination without imaging the edge down to the atomic scale of monolayer hexagonal boron nitride (h-BN), enabling a direct comparison to theoretical predictions. Another important issue in 2D materials research is the determination of the layer count and its lateral spatial uniformity. In this work, a method is developed to map the layer count of a 2D material at nanometer-scale lateral resolution over extended areas, utilizing a combination of mass-thickness mapping offered by STEM and element-specific quantization afforded by electron energy loss spectrum (EELS) mapping. The last part of this thesis work unravels the multiple mechanisms behind the behavior of field effect transistors (FETs) based on PdSe2. The change in device behavior in early reports from ambipolar to n channel was puzzling. As commonly encountered in device research, many factors, including channel material properties, defects, contaminants, and contact effects, are almost always entangled. Here, I use multiple control devices to unravel various mechanisms and provide consistent explanations for device behvior variations.

Download or read book Two dimensional Materials Synthesis Characterization and Devices written by Harry Chou and published by . This book was released on 2018 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two dimensional materials have unique properties that are anisotropic in-plane and out-of-plane. They further exhibit unique properties when they are thinned down to an isolated monolayer or a few layers. These properties have the potential to greatly impact applications in energy, computing, construction, medicine, and other industries. Many researchers have published many reports working with two dimensional (2D) materials. This dissertation describes work which has contributed to the body of research around 2D materials synthesis, characterization, and device applications primarily with graphene and hexagonal boron nitride. Graphene is a hexagonal lattice of carbon atoms which is stable in ambient down to a single monolayer. Hexagonal boron nitride is an isomorph of graphene but with boron and nitrogen atoms on the lattice instead of carbon. Chemical vapor deposition (CVD) synthesis processes have shown to be replicable and capable for obtaining 2D materials of high quality, and experimenting with process conditions has improved the understanding about the synthesis mechanisms occurring. The objective of my 2D materials synthesis work is, broadly, to better understand the mechanisms during growth for graphene and h-BN. The growth mechanism has multiple of forces acting on it, in competition, and many of them are detailed in chapter 2. Growing the body of research and knowledge about 2D materials requires us to have techniques to characterize these materials accurately and precisely. It is important to develop and demonstrate new characterization techniques which are tailored for 2D materials. In chapter 3, the research done in characterizing 2D materials and interfaces between hetero-layers will be presented. Devices which take advantage of the dimensionality and confinement within a layer of 2D material, or multiple materials, have shown high performance in a variety of applications. The range for 2D materials device applications is continually expanding and increasing in complexity. In chapter 4, research will be presented which returns to the relatively simple system of graphene to try and apply its many unique properties for a few different photovoltaic devices
