▎ 摘　　要

NOVELTY - The infrared sensor (1) has a first graphene layer (21) that is provided to absorb infrared rays by utilizing plasmon resonance. A second graphene layer (22) is provided with a connection portion (22A) that is connected to the first graphene layer. A first electrode (31) and a second electrode (32) are connected to the second graphene layer with the connection portion. A control electrode (40) is provided to asymmetrically control the Fermi energy distribution of the second graphene layer between the first electrode and second electrode. The control electrode is provided with a third electrode (43) that is arranged between the first electrode and second electrode in a plan view. USE - Infrared sensor for detecting thermal radiation used for night vision and thermography at night. ADVANTAGE - The infrared sensor has high light absorption efficiency and high thermoelectric conversion efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a plan view of the infrared sensor.
