<title>Low-frequency noise spectra of high-quality MCT photoconductors</title>

Abstract

Low-frequency flicker-noise "1/f' spectra were examined on Photoconductive Mercury-Cadmium Telluride I Hg1CdTe (PC MCT) infrared radiation detectors. Noise measurements were perfonned on PC MCT detectors with responsivity peak wavelength 2 from 3,0 to 5,5 xm and from 10,5 to 12,0 m at operating temperature T 205 -210 K and 78 K respectively. Tested high quality PC MCT infrared radiation detectors show extremely low spectral density of excess "1/f' noise and low values of noise-knee frequency from 10 to 150 Hz and demonstrate high-level performance.
