Abstract
A photocapacitor device is provided for responding to a photon having at least a specified energy. The photocapacitive device includes a first portion composed of a photocapacitive material; a second portion composed of a non-photocapacitive material; and a depletion region disposed between the first and second portions. The photocapacitive and non-photocapacitive materials respectively have first and second Fermi-energy differences, with the second Fermi-energy difference being higher than the first Fermi-energy difference.
