Abstract
The photoelectromagnetic (PEM) effect has been successfully used for the detection of IR radiation in the past,1 In consequence of high-electron mobility, indium antimonide has commonly been used for the detector's construction. Unfortunately the cutoff wavelength for these detectors is ~ 7μm, and they cannot be used for CO2 laser beam control. During the last few years, however, mercury cadmium telluride (MCT) was extensively studied in Poland2 as a material for PEM detector fabrication.
