▎ 摘　　要

NOVELTY - Fabricating graphene layer involves cleaning, seeding a substrate, depositing crystalline diamond on the substrate, sputtering an aluminum layer on the crystalline diamond, where the aluminum layer is greater than 5-50 nanometer, treating a surface of the aluminum layer with an ion beam damaging an interface between the aluminum layer and the crystalline diamond, and converting the aluminum layer into the graphene layer on the crystalline diamond. USE - Method for fabricating graphene layer. ADVANTAGE - The method enables to fabricate graphene layer in simple manner. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a diamond graphene metal structure. 402Substrate 404Diamond layer 406Graphene layer 408Metal layer
