Abstract:
　　The boom of graphene research has stimulated great interest in two-dimensional form by other elements, either single element or composite materials. Among these 2D materials special interest have been paid on those formed by carbon neighbors, such as group IV elements (Si, Ge, Sn), and its neighboring element, boron and nitrogen. 2D materials formed by carbon neighbors may possess intriguing structural and electronic properties closely related, but also differ from that of graphene. In this talk we will present our recent experimental works on 2D materials, for examples silicene and 2D boron. I will focus on MBE growth, and structure and electronic characterizations by STM.
