▎ 摘　　要

NOVELTY - A graphene top electrode preparing method involves transferring the graphene to polydimethylsiloxane by wet or dry transfer method. The graphene transferred to the polydimethylsiloxane is laminated to the organic functional layer of the semiconductor device together with the polydimethylsiloxane followed by tightly adhering graphene on the polydimethylsiloxane by Van der Waals force to the organic functional layer as the top electrode of the device. USE - Method for preparing graphene top electrode for a semiconductor device. ADVANTAGE - The method enables preparing graphene top electrode in simple, convenient, and cost effective manner.
