项目摘要
Non-technical Abstract:A grand challenge in materials research is the preparation of novel compounds with designed properties. The ability to create stable layered materials with complicated layering schemes provides an unprecedented ability to probe the interplay between structure, composition, and physical properties of the constituents. This research produces a rich collection of new materials with diverse and highly unusual properties and an improved understanding of structure-property relationships in compounds containing structurally different layers. A goal is to understand the dependence of physical properties on the identity, thickness, and the sequence of individual layers. A second goal is to understand the fundamental aspects of the synthesis approach that result in the preparation of stable products. Current and future technologies crucial to international competitiveness depend on being able to both prepare and characterize stable layered materials to obtain enhanced properties, which are not found in any of the individual components. Technical Abstract:This research extends a synthesis approach to create new, layered solids containing two or more structurally different constituents with atomically abrupt interfaces between them. Designed precursors enable kinetically stable heterostructures with designed nanoarchitectures to be prepared over large areas. The project goal is to understand the dependence of transport properties on nanoarchitecture in heterostructures containing electrically isolated two dimensional layers of transition metal dichalcogenides, bismuth chalcogenides and related ternary structures. Large band gap spacer layers of varying thickness electrically isolate the dichalcogenide monolayers and adjacent magnetic layers are used to perturb the monolayers. This research is timely, as recent discoveries promise advances in a variety of technologies including tunnelling transistors, flexible electronics, photodetectors, photovoltaics and light-emitting devices with unprecedented characteristics and/or unique functionalities. This research provides a broad technical background for graduate students in deposition technologies, thin film characterization techniques, and physical phenomena that occur in 2D heterostructures. This training enables them to thrive in careers in high tech industries, academia or national laboratories.
非技术摘要:材料研究中的一个巨大挑战是制备具有设计性能的新型化合物。用复杂的分层方案产生稳定的分层材料的能力提供了前所未有的能力来探测组分的结构、组成和物理性质之间的相互作用。这项研究产生了丰富的新材料,具有不同的和非常不寻常的特性,并提高了对含有结构不同层的化合物的结构-特性关系的理解。一个目标是了解物理性质的依赖性的身份,厚度和顺序的各个层。第二个目标是了解导致制备稳定产品的合成方法的基本方面。目前和未来的技术对国际竞争力至关重要,这取决于能够制备和表征稳定的层状材料,以获得增强的性能,这在任何单个组件中都没有发现。技术摘要:这项研究扩展了一种合成方法,以创建新的,分层的固体包含两个或两个以上的结构不同的成分与原子之间的突然界面。设计的前体使得能够在大面积上制备具有设计的纳米结构的动力学稳定的异质结构。该项目的目标是了解在异质结构包含过渡金属二硫属化物,铋硫属化物和相关的三元结构的电隔离的二维层的纳米结构的输运性能的依赖。不同厚度的大带隙间隔层电隔离二硫属化物单层,并且相邻的磁性层用于扰动单层。这项研究是及时的,因为最近的发现预示着各种技术的进步,包括隧道晶体管,柔性电子器件,光电探测器,光电子器件和具有前所未有的特性和/或独特功能的发光器件。这项研究提供了一个广泛的技术背景,研究生在沉积技术,薄膜表征技术,并在2D异质结构中发生的物理现象。这种培训使他们能够在高科技行业,学术界或国家实验室的职业生涯中茁壮成长。
