▎ 摘　　要

NOVELTY - Direct growing of graphene involves arranging a substrate in a chamber having a target surface on which graphene is to be grown, feeding a catalyst gas containing a raw material gas containing a carbon-containing compound and a germanium-containing compound into the chamber, and growing a graphene layer on the target surface. USE - Direct growing of graphene (claimed). ADVANTAGE - The method enables direct growing of graphene without using a metal catalyst layer.
