Graphene structure having graphene bubbles and preparation method for the same

Abstract

The present invention provides a graphene structure having graphene bubbles and a preparation method for the same. The preparation method comprises: providing a substrate; forming a hydrogen terminated layer on a top surface of the substrate and a graphene layer disposed on a top surface of the hydrogen terminated layer; and placing a probe on the graphene layer and applying a preset voltage to the probe, to excite a part of the hydrogen terminated layer at a position corresponding to the probe to convert into hydrogen, the hydrogen causing the graphene layer at a position corresponding to the hydrogen to bulge, so as to form a graphene bubble enveloping the hydrogen.
