Abstract

Disclosed are infrared (IR) light detectors. The detectors operate by generating hot electrons in a metallic absorber layer on photon absorption, the electrons being transported through an energy barrier of an insulating layer to a metal or semiconductor conductive layer. The energy barrier is set to bar response to wavelengths longer than a maximum wavelength. Particular embodiments also have a pattern of metallic shapes above the metallic absorber layer that act to increase photon absorption while reflecting photons of short wavelengths; these particular embodiments have a band-pass response.
