Abstract
A method of transferring graphene, the method including: preparing a graphene forming structure including a base member, an oxide layer that is hydrophilic and is formed on the base member, a metal catalyst layer that is hydrophobic and is formed on the oxide layer, and graphene that is formed on the metal catalyst layer; attaching the graphene forming structure on a surface of a first carrier; separating the oxide layer from the metal catalyst layer by applying steam to the graphene forming structure; and removing the metal catalyst layer.
