Graphene
Graphene is a material that is 100 times more electrified than copper. Not only does the electron travel 100 to 150 times faster than silicon used as a semiconductor raw material, but it is also light and flexible, with a strength of more than 200 times that of steel, so it can be used as various materials. Another characteristic of graphene nanomaterial is that it is a transparent material that passes through most of the light.
