英文摘要： The two-dimensional graphene is considered to be the most potential post-silicon material for the next generation photoelectronics, and scientists have developed many relevant devices including field effect transistors (FET) though are being faced with a lot of challenges. The aim of the present project is to design novel nano-photoelectronic devices based on graphene, and systematically deals with three substantial problems: How to determine the nanostructure that owns desired photoelectronic properties? How to prepare the nanostructure, and how to predict and modify their thermal stability？ Specifically, we would further develop the single atom statistical model proposed recently by the applicant for predicting the thermal stability and lifetime of nanodevices, which will be applied to optimize the new electrical rectification devices and a novel nano-laser based on nano carbon chains proposed by ourself recently, and to explore novel type of FET based on graphene, and so on.
