▎ 摘　　要

NOVELTY - A graphene-based infrared absorber layer consists of a thermosensitive layer, a graphene film provided on the thermosensitive layer, and a silicon nitride film provided below the thermosensitive layer. USE - Graphene-based infrared absorber layer used for manufacturing infrared detector (all claimed). ADVANTAGE - The graphene-based infrared absorber layer has excellent greenhouse effect due to use of thermosensitive layer. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) infrared detector, which consists of a substrate with a readout circuit, the graphene-based infrared absorber layer, and a reflective layer; and (2) manufacture of infrared detector.
