Far‐Infrared Interband Magnetoabsorption and Band Structure of Hg1−xCdxTe Alloys

Magnetoabsorption experiments on n‐type Hg1−xCdxTe alloy crystals (x = 0, 0.07, 0.126, 0.148) have been performed in the Faraday geometry in the spectral region 4 to 40 meV at 4.2 K and with magnetic fields up to 50 kOe. In the analysis of the spectra we have used the formulae collectively including the exact interactions among the T8,T6, and T7, bands. Our experimental results and the computed energies indicate that „the modified Luttinger parameters”︁ of the T8 bands are common to samples with various x‐values (x < 0.158).
