▎ 摘　　要

NOVELTY - Preparation of continuous single layer graphene on an insulating substrate comprises providing an insulating substrate, depositing germanium film on the insulating substrate, using germanium film as catalyst, growing graphene at high temperature, continuously evaporating germanium film at high temperature, and completely removing to obtain continuous graphene bonded on the insulating substrate. USE - Preparation of continuous single layer graphene on an insulating substrate (claimed). ADVANTAGE - The method is simple and provides product with improved quality and performance.
