Abstract

A very long photoresponse time and the other drawbacks of extrinsic photoconductors used as low-background IR detectors are caused by the trap memory being uncontrolled at the operation under a constant 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.
