▎ 摘　　要

NOVELTY - The structure has a copper layer, and two graphene layers that sandwich the copper layer. Electron-path tunnels are provided between the copper layer and the graphene layers. The graphene layers are one of a graphene monolayer and a graphene bi-layer. The copper layer is comprised of a crystallographic orientation. A first graphene layer, a first copper layer on the first graphene layer, a graphene bi-layer on the first copper layer, a second copper layer on the graphene bi-layer, and a second graphene layer on the second copper layer are provided. USE - Multilayer composite structure used in industrial applications. ADVANTAGE - The energy consumption is reduced, and the benefits for downscaled electronics are offered. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for forming the multilayer structure. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating the process for forming multilayer structure.
