Two-dimensional (2D) materials are at the forefront of research in quantum phenomena in condensed matter, with many research groups worldwide currently exploring their fundamental properties and applications. A large number of different types of 2D materials exist and each offer a wide variety of different properties. These monolayers can be stacked to create van der Waals (vdW) heterostructures that are designed with specific "built-in" device functionality. The properties of these stacks depend critically on their layer configuration and can be dramatically modified by controlling the relative "twist" angle between the lattices of the layers. In this project, the student will develop models to understand and predict new quantum transport phenomena of electron moving between and within the layers of novel vdW heterostructures. They will investigate different layer configurations of graphene with the 2D post transition metal chalcogenides (a class of 2D semiconductors with excellent electronic properties) and consider the effect of "twist" angle and magnetic fields.

二维（2D）材料是凝聚态量子现象研究的前沿，目前全球许多研究小组正在探索其基本性质和应用。存在大量不同类型的2D材料，每种材料都提供各种不同的属性。这些单层可以堆叠以产生货车德瓦耳斯（vdW）异质结构，其被设计为具有特定的“内置”器件功能。这些叠层的性质主要取决于它们的层结构，并且可以通过控制层的晶格之间的相对“扭曲”角来显著地修改。在这个项目中，学生将开发模型来理解和预测电子在新型vdW异质结构层之间和层内移动的新量子传输现象。他们将研究石墨烯与2D后过渡金属硫属化物（一类具有优异电子特性的2D半导体）的不同层配置，并考虑“扭曲”角度和磁场的影响。
