Abstract
A photodetector/imaging device comprises a layer of photoconductive material converting incident electromagnetic radiation into electrical charges, the layer of photoconductive material being capable of avalanche multiplication when an electric field of sufficient magnitude is applied thereacross; a readout layer detecting the electrical charge; and at least one interface layer between the layer of photoconductive material and the readout layer, the interface layer coupling electrical charge to or from the layer of photoconductive material and being configured to inhibit uncontrolled rises in current in the photoconductive material during avalanche multiplication.
