▎ 摘　　要

NOVELTY - The method involves obtaining a pyroelectric crystal substrate. A nickel chromium alloy layer is deposited at a side of the pyroelectric crystal substrate to form an upper electrode by utilizing a radio frequency magnetic sputtering process. A graphene infrared absorption layer is deposited on the upper electrode. A lower electrode is bonded with a high impedance substrate. A surface of the graphene infrared absorption layer is processed to form a nano-shaped infrared sensitive absorbing layer. The pyroelectric crystal substrate is selected as a lithium wafer. USE - Method for manufacturing a pyroelectric infrared detector graphene absorbing layer (claimed). ADVANTAGE - The method enables improving surface compactness, absorption coefficient and heat response performance and reducing heat loss. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a method for manufacturing a pyroelectric infrared detector graphene absorbing layer.'(Drawing includes non-English language text)'
