Scientific paper

Low-frequency flicker-noise "1/f" spectra were examined on Photoconductive Mercury-Cadmium Telluride / Hg1-xCdxTe (PC MCT) infrared radiation detectors. Noise measurements were performed on PC MCT detectors with responsivity peak wavelength λp from 3,0 to 5,5 µm and from 10,5 to 12,0 µm at operating temperature Top ≈ 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.
