Yang Han

Novel nanostructures have been fabricated continuously with the help of the development of nanotechnology. These structures have a series of greatly different physical properties from their bulk counterparts, making them to have a great potential application in the physics, chemistry, materials science, biology and life science, nanoelectronics and nanotechnology. Research on two-dimensional (2D) materials such as graphene and graphene-like group-IV materials is of fundamental scientific interest from the view of the variety of applications. For example, graphene possesses extreme mechanical strength, exceptionally high electrical and thermal conductivities, as well as many other supreme properties, all of which make it highly attractive for numerous applications. Inspired by the prospective properties of graphene, there has been increasing interest in its ???cousins???, i.e., two-dimensional honeycomb lattices composed of other group-IV elements, e.g. Si and Ge, which naturally have been considered to have a graphene-like hexagonal structure with similar exceptional properties. Layered silicon oxide is also an important building block that provides insulating barriers in electronic devices, e.g. as a gate oxide in field effect transistors. Moreover, thin silica films grown on metal single crystal substrates can be used as model systems for studying the structure-property relationships of silica and related materials using surface science techniques. This talk mainly focuses on the mechanical, electronic, magnetic and thermal transport properties of the two dimensional (2D) graphene-like materials.
