【 摘 要 】
We present both numerical and analytical studies of graphene roughness with a crystal structure including 500x500 atoms. The roughness can effectively result in a random gauge field and has important consequences for its electronic structure. Our results show that its height fluctuations in small scales have a scaling behavior with a temperature dependent roughness exponent in the interval of 0.6
