▎ 摘　　要

NOVELTY - An optoelectronic device consists of one or more layers of graphene, and one or more layers of molybdenum sulfide film deposited on a substrate (A). The optoelectronic device has a hetero-hybrid structure formed by providing graphene layer on molybdenum sulfide films. The graphene is transferred on the top of molybdenum sulfide in a continuous sheet forming the in-plane geometry. USE - Optoelectronic device e.g. switch device, sensor device, and memory device (all claimed) is used for electronic and photonic devices e.g. high-mobility transistor, solid-state laser, light-emitting device, and solar cell. ADVANTAGE - The optoelectronic device has excellent light sensitivity, gate tunability, and optical transparency, and controllable electrical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for optoelectronic device development method.
