▎ 摘　　要

NOVELTY - The transistor has a substrate formed with a gate electrode metal layer, a grid electrode medium layer, a graphene-containing layer and a source and drain electrode metal layer. The source and drain electrode metal layer is provided with a periodic micro-nano structure. The periodic micro-nano structure is linked to the gate electrode metal layer and the grid electrode medium layer to form complete absorption property structures. A gate dielectric layer is made of low optical absorption dielectric material that is selected from one of silicon oxide, silicon nitride or aluminum oxide material. USE - Meta-material structured graphene transistor for an optical detector e.g. spectrum detection device or image sensing apparatus (all claimed). ADVANTAGE - The transistor has high sensitivity and better narrow band response effect, and can work in visible light. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a meta-material structured graphene transistor.
