Is graphene a new inorganic nonmetallic material?

Graphene is a semi-metal between conductor and semiconductor. First, large-area graphene is not a semiconductor, and graphene nanobelts are semiconductors. Theoretically, it is a transparent conductor with an energy band of 0. But according to different preparation methods, different preparation methods lead to different properties of graphene. In the semiconductor industry, the process of chips has always obeyed Moore's law, and the end of silicon chips means that new materials must be replaced. Silicon belongs to semiconductor, and its energy band is 1. 12ev, so many groups want to modify, force or change the size by doping to open the energy band of graphene.
