Abstract
A method of operating a photodetector system. The method impresses a surface charge on a photon detector by establishing an electric potential across the detector, storing the detector in the dark, disconnecting the source of electric potential, and electrically connecting layers in the detector.
Claims3
A method of impressing a uniform surface charge on a multilayered photon detector having sequentially stacked in plane parallel a first conducting layer, a junction layer, a photoconductive layer, an insulating layer, and a transparent conductive layer comprising:
- connecting a high electric potential across the first conducting layer and the transparent conductive layer;
- storing the detector in the dark;
- disconnecting the source of external electric potential while said detector is in the dark;
- electrically connecting said first conducting layer to said transparent conducting layer while said detector is in the dark;
- and
- reapplying the potential with reversed polarity between said first conducting layer and said transparent conducting layer while said detector is in the dark.
