• deposition; electronic state analysis; graphene oxide; X-ray absorption fine structure; Introduction Graphene oxide (GO) is oxidized graphene and its surface and periphery are partially modified by epoxy, hydroxy, and carboxy functional groups [1][2]. GO can be thinned to a monolayer of one carbon atom and
