SCHOTTKY BARRIER PHOTOVOLTAIC DETECTOR

摘要

A Platinum-cadmium sulfide schottky barrier photovoltaic detector which is capable of sensing near ultraviolet and short wavelength visible radiation with extremly small response to wavelengths longer than about 5200 angstorms. The detector is gabricated with both the ohmic and barrier contacts located on the same side of the cadmium sulfide substrate to facilitate wire attachment by high-speed bonding techniques. A titanium-gold-titanium infrared shield structure is deposited directly on the substrate and is utilized to provide a connection between the ohmic contact and the substrate.
