Abstract :
Photoconductive detectors were fabricated on semi-insulating liquid phase epitaxial In0.53Ga0.47As/InP doped with Fe for the first time. Their performance characteristics have been compared with identical devices made from Zn-doped p-In0.53Ga0.47As/InP. Internal optical gains up to 10 were measured in the Fe-doped devices. The bias and intensity-dependent gain characteristics of these devices are discussed.
