▎ 摘　　要

NOVELTY - The detector has a substrate (1), a graphene layer (4) and an electrode layer (7). A first light-transmitting layer (3) and a second light-transmitting layer (5) are respectively provided on both sides of the graphene layer. A first reflective layer (2) is arranged between the substrate and the first light-transmitting layer. A second reflective layer (6) distributed at intervals is arranged between the electrode layer and the second light-transmitting layer. The first reflective layer, the first light-transmitting layer, the second light-transmitting layer and the second reflective layer jointly form an optical microcavity structure. USE - Graphene near infrared detector with optical microcavity structure. ADVANTAGE - The detector is simple in structure, and has high infrared absorption rate and stable and reliable work. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing a graphene near infrared detector with optical microcavity structure. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene near infrared detector with optical microcavity structure.
