石墨烯是一种由sp(2)键合的碳原子的二维单分子膜，由于其独特的输运性质而引起了人们的极大兴趣。石墨烯具有较高的光学透过率和导电性，作为透明导电电极具有广阔的应用前景。本文报道了用化学气相沉积法在铜箔上生长大面积石墨烯的一种改进的转移工艺。转移后的石墨烯薄膜具有高电导率和高透光率，适合于透明导电电极的应用。改进后的转移工艺对场效应晶体管和双层伪自旋场效应晶体管等电子器件的制备也具有重要的应用价值。
Graphene, a two-dimensional monolayer of sp(2)-bonded carbon atoms, has been attracting great interest due to its unique transport properties. One of the promising applications of graphene is as a transparent conductive electrode owing to its high optical transmittance and conductivity. In this paper, we report on an improved transfer process of large-area graphene grown on Cu foils by chemical vapor deposition. The transferred graphene films have high electrical conductivity and high optical transmittance that make them suitable for transparent conductive electrode applications. The improved transfer processes will also be of great value for the fabrication of electronic devices such as field effect transistor and bilayer pseudospin field effect transistor devices.
