Abstract
This disclosure is directed to a photovoltaic detector having specific response to the infrared range, wherein the detector comprises a metal-semiconductor diode having a semi-transparent electrode and disposed on a specially prepared substrate of a narrow band gap semiconductor material or on an epitaxial layer or evaporated film of such material provided on a substrate. In a specific example, the narrow band gap semiconductor material of the substrate is specially prepared (Pb,Sn)Te or an epitaxial layer or evaporated film of (Pb,Sn)Te on a (Pb,Sn)Te substrate. The detected radiation is transmitted through the semi-transparent electrode on top of the photovoltaic detector.
