GRAPHENE AND ITS GROWTH

Research output: Patent

Abstract

The present invention provides graphene nuclei including monolayer single-crystalline graphene nuclei and a method of growing from them two-dimensional graphene dendrites, with aspect ratio of the main branches increasing with growth time, on catalytic metal surface using thermal chemical vapor deposition. By controlling the supply rates of the carbon etching gas and the carbon deposition species, it results in graphene branches being merged to form a two-dimensional monolayer single-crystalline graphene plate and further allows multiple graphene plates to merge and form a large-area continuous monolayer graphene plate.
