Infrared absorption in In-doped degenerate Hg1−xCdxTe

Abstract The infrared absorption spectra, including absorption edge spectra and below-gap absorption spectra, were investigated both experimentally and theoretically for an In-doped degenerate HgCdTe sample with an electron concentration N e = 7.0 × 10 17 cm -3 for wavelengths 7 μm L T N imp =3.4 × 10 18 cm -3 . A good account of the behaviour of absorption edge in the light of Burstein-Moss effect has also been given.
