▎ 摘　　要

NOVELTY - The method involves forming a multi-layer in a graphene forming die. Liquid metal is fixed on a solid substrate or ceramic metal. An outer layer of the liquid metal or alloy metals is fixed at a melting point. Range of the melting point is maintained upto 1151-3410 degree Centigrade. Partial pressure of ethylene is 0-4 hPa. Hydrogen partial pressure of the ethylene is 0-2 hPa. Atmosphere of pure constant argon partial pressure is 1-1100 hPa. USE - Method for producing a graphene layer.
