英文摘要：

Due to its special structure,graphene has very good optical,electrical,mechanical and other properties,and it is regarded as a breakthrough of the new materials. Thanks to the wide band gap,thermal stability,high working power and other properties,GaN based materials have become＂the most important,after the silicon semiconductor material. ＂It will bring great benefits for the photoelectric and microelectric devices if the graphene can be successfully combined with GaN based materials. There have already been some breakthroughs in the research of combination of graphene and GaN based materials. This paper briefly summarized recent findings of physical mechanisms of the contact between graphene and GaN-based materials and the researches of the applications of graphene to the GaN-based materials.
