ABSTRACT:
A novel multilayer photoconductive I.R. detector is formed by incorporating alternate p and n-type layers, such that many layers occupy the detector thickness. The detector may be considered as a n-type photoconductor containing buried isolated p-type regions which give rise to internal electric fields the effect of which is to enhance minority carrier lifetime and inhibit motion of minority carriers towards surfaces.
