"Controlled by light, Schottky junctions suppress or permit rectification behavior of n/n− junction... output current photon-controlled diode change from fully-off to rectified state... light-to-dark rectification ratio... more than 106... photodetector, its responsivity exceeds 105 A/W... by increasing thickness photogating layer, behavior device changes to a multifunctional photomemory with highest nonvolatile responsivity 4.8×107 A/W and longest retention time of 6.5 × 106 s reported so far"
