ABSTRACT:
An electrical field sustained conductivity device is fabricated by successively disposing over a layer of cadmium sulfide a film of metal particles and a composite layer of metal particles in an insulating medium. When a potential is applied across the cadmium sulfide layer, an image may be stored therein by momentarily exposing the layer to electrons or light conveying that image. Such exposure introduces conductivity changes in the cadmium sulfide layer by virtue of the layers deposited on it and the conductivity changes are retained so long as the applied potential is maintained.
