▎ 摘　　要

NOVELTY - The method involves flatly packing a collection of scaly graphite particles or a collection of lump graphite particles on a surface of one of the two parallel plate electrodes. The parallel plate electrode is immersed in methanol filled in a container. The other parallel plate electrode is superposed on the one parallel plate electrode. The two parallel plate electrodes are separated from each other through the aggregate of the scaly graphite particles or the aggregate of the massive graphite particles. The two separated parallel plate electrodes are immersed in the methanol, and a direct current potential difference is applied to gap between the two parallel plate electrodes. The electric field corresponding to the value obtained by dividing the magnitude of the potential difference by the size of the gap between the two parallel plate electrodes is generated. USE - Method for producing graphene junction composed of collection of graphene. ADVANTAGE - The process for effectively producing graphene junction composed of collection of graphene is realized. The graphene junction near the property of a graphene is manufactured in low cost. DETAILED DESCRIPTION - The all of the interlayer bonds of the basal plane forming the scaly graphite particles or the massive graphite particles are simultaneously destroyed by applying the electric field. A collection of graphene corresponding to the basal plane is produced in the gap between the two parallel plate electrodes, and then the gap between the two parallel plate electrodes is expanded. The two parallel plate electrodes are tilted in the methanol, and vibrations in three directions of left-right, front-back, and up-down are repeatedly applied to the container to collect the graphene. The two parallel plate electrodes are moved into the methanol through the gap between the two parallel plate electrodes, and then the two parallel plate electrodes are taken out from the container. The vibrations in three directions, front and back, left and right, and up and down, are repeatedly applied to the container. A collection of graphene in which the flat surfaces of the graphene are overlapped with each other through methanol is formed on the bottom surface of the container as the shape of the bottom surface. The temperature of the container is raised to the boiling point of the methanol to vaporize the methanol. A collection of graphene in which the flat surfaces of the graphene are overlapped is formed on the bottom surface of the container as the shape of the bottom surface. The plane above the graphene cluster is evenly compressed, and the frictional heat is generated at the portion where the flat planes of the graphene overlap each other. A graphene junction composed of a collection of graphene obtained by joining the flat planes of the graphene to each other by the frictional heat and joining the flat planes in which the flat planes of the graphene overlap each other is formed.
