Single-step formation of graphene on dielectric surfaces

Abstract

The direct formation of graphene on various dielectric surfaces is successful via a single-step rapid thermal processing (RTP) of substrates coated with amorphous carbon (C) and nickel (Ni) thin films. High-quality graphene is obtained uniformly on the whole surface of wafers with a controlled number of graphene layers. The monolayer graphene exhibits a low sheet resistance and a high optical transmittance in the visible range.
