Abstract: The photoresponse is investigated in the frequency range of 0.15 – 15 THz in HgCdTe epitaxial layers with a cadmium concentration from 15.2 to 19.2% grown by molecular-beam epitaxy. It is shown that narrow-gap and gapless HgCdTe solid solutions can be used as detectors of both terahertz and sub-terahertz radiation with a characteristic response time of 2 – 4 ns and with a sensitivity approaching n -InSb-based detectors widely used in this range.
Keywords: terahertz radiation, HgCdTe, photoelectric detectors, photoconductivity.

The sensitivity measurements of structures based on HgCdTe in the sub-THz range, as well as measurements of the CR spectra for analyzing gyrotron radiation, were supported by the Russian Science Foundation, grant no. 18-79-10112. Investigations of the spectra and the kinetics of the photoresponse in the spectral range of 5–15 THz were supported by a grant from the President of the Russian Federation for the state support of young Russian scientists—candidates of sciences (MK-1430.2020.2).
