Semiconductor photodiodes and electroabsorption in far-infrared mercury - cadmium - telluride

The far-infrared (FIR) portion (8-14;The Franz-Keldysh effect may be used to electrically shift the absorption of a semiconductor material from nonabsorbing to absorbing states for a given wavelength. We investigated the use of Franz-Keldysh Electroabsorption photodetector as an overload protected device at the 10.6;The MIS-type devices displayed photovoltaic response to optical excitation for wavelengths from 5...
