Abstract
A technique for forming graphene which solves problems involved in formation of graphene by a thermal CVD method and a resin carbonization method that a high temperature is used and the treatment time is long and can form graphene at a lower temperature in a shorter time is provided. The above problems are solved by performing hydrogen plasma treatment on a copper foil substrate having an organic substance applied thereon by use of a surface wave microwave plasma treatment device and forming graphene on the copper foil substrate by the hydrogen plasma treatment.
