▎ 摘　　要

NOVELTY - The detector has a first electrode and a second electrode provided with two inner wall of a cavity. An end of a graphene is located on the first electrode. Another end of the graphene is located on the second electrode. The graphene is separated from a wall of the cavity. The first electrode and the second electrode are fixed with a through hole that is oppositely connected with the graphene. A crystal layer is fixed with the through hole, where material of the crystal layer is made of a Cadmium telluride crystal particles and Molybdenum Oxide crystal particles. USE - Graphene Johnson noise measurement based infrared detector. ADVANTAGE - The detector obtains thermal noise of graphene by detecting change in temperature of graphene and relationship between temperature change of graphene and thermal noise, and directly obtains irradiated wavelength of infrared light on the graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene Johnson noise measurement based infrared detection system. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a graphene Johnson noise measurement based infrared detector.
