ABSTRACT:
High quantum yields are provided by sandwiching an insulating layer in contact with a photoconductor between two electrodes. The sandwiched structure in conjunction with an applied electrical potential and excitation light provides an electrical switching device. Optionally, an imaging layer can be included between the photoconductive layer and one of the electrodes, and can be imaged with increased sensitivity.
