More Information
Summary:An infrared photo-detector array and a method for manufacturing it are disclosed. The infrared photo-detector array contains a plurality of pyramid-shaped structures, a first light-absorbing material supporting the plurality of the pyramid-shaped structure, a carrier-selective electronic barrier supporting the first light-absorbing material, a second light-absorbing material supporting the carrier-selective electronic barrier, and a metal reflector supporting the second light-absorbing material, wherein the plurality of the pyramid shaped structures are disposed on the side of the photo-detector array facing the incident light to be detected and the metal reflector is disposed on the opposite side of the photo-detector array. The method disclosed teaches how to manufacture the infrared photo-detector array.
