Abstract

A very long photoresponse time and other drawbacks of extrinsic photoconductors used as low-background IR detectors are caused by their trap memory being uncontrolled at the operation under a fixed voltage. A proper pulsed voltage allows to control the memory. Below the principles of the control are set forth, and the brief theory of one of the operation modes with the controlled trap memory is given. This serves as the basis for further analysis of several detectors operated under such modes and for the notions applied to a drastic improvement of the performance of space IR detectors.
