▎ 摘　　要

NOVELTY - The electron and optical device (1) has a laminated structure, in which an intermediate layer is arranged between a layered substance material layer (2) and a metal electrode layer (3). The intermediate layer is taken as a crystal layer (4) of an intermediate layer made of antimony, and Bismuth and Tellurium. The layered substance material layer is formed by including semiconductor transition metal dichalcogenide and graphene. A gate electrode is arranged on the layered substance material layer through an insulating film (5). A source electrode portion is constituted by laminating the intermediate layer and the metal electrode layer on the laminar substance material layer. USE - Electron and optical device for use in electronic device. ADVANTAGE - The contact resistance that occurs between a layered substance material layer and a metal electrode layer is reduced. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing an electron and optical device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the electron and optical device.
