Abstract
Official abstract text for this publication.
Provided is a graphene substrate, which is manufactured by: bringing a metal layer into contact with a carbon-containing layer and heating the metal layer to dissolve carbon in the carbon-containing layer into the metal layer; and cooling the metal layer to precipitate the carbon in the metal layer as graphene on any substrate surface.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of manufacturing a graphene substrate, comprising the steps of: (a) bringing a metal layer into contact with a carbon-containing layer and heating the metal layer to dissolve carbon in the carbon-containing layer into the metal layer; and (b) cooling the metal layer to precipitate the carbon in the metal layer as graphene on a surface of a heat-resistant material brought into contact with the metal layer to allow the metal layer to become li…
