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.
