Abstract
An array of semiconductive photoconductor detectors is formed on a substr with which the array forms a heterojunction. The array has a whole or partial overlayer of the same material as the substrate. Ohmic connections are made on the detectors and conductive read-out leads are connected to these connections; the leads are made of a conductor that forms a Schottky barrier with the substrate and overlayer. Ohmic connections are made to the substrate and overlayer such that a voltage bias may be applied between the substrate-overlayer combination and the array. The bais is used to control the accumulation layer in the substrate beneath the array in order to maximize sesitivity.
