Modulating the electronic structure of two-dimensional heterostructures.

Since the discovery of graphene, two-dimensional (2D) materials have attracted great attention mainly due to their unique physical properties and capability to fulfill the demands of future nanoelectronic industry on flexibility. Up to now various 2Dmonolayers have been synthesized experimentally, and they show many interesting features which are promising for technological applications such as field effect transistors, solar cells, and light emitting diodes. Combing different 2D materials into a single structure results in 2D heterostructures. 2D heterostrutures can have new properties different from the constituents, allowing the development of new devices in spintronics, optoelectronics and solar energy conversion. To achieve realistic applications, understanding and manipulating the electronic properties of 2D heterostructures is of importance. In this project, we investigate the effects of different factors, such as interface, composition of different materials and strain, on the properties of silicene/silicane superlattices and MX2 heterostructures. The aim is to provide theoretical guidance to tune the electronicand magnetic properties of 2D heterostructures.
