▎ 摘　　要

NOVELTY - A suspended graphene is transferred by (1) fixing a mask material on metal substrate with graphene by chemical vapor deposition, and vapor depositing metal over the graphene; (2) removing metal mask material that has a structural layer of metal/graphene/metal substrate in etching solution after etching metal substrate to form a structural layer of metal/graphene; and (3) washing layer structure of metal/graphene, removing with hollow substrate and drying. USE - Transferring a suspended graphene. ADVANTAGE - The method adopts multiple mask material to graphene surface for depositing a metal. The mask material fixed on graphene surface can be obtained after different area of exposed graphene. Graphene can obtain different suspending area after etching transfer to realize a controllable area of suspended graphene transfer.
