Abstract
Absorption spectra of p-MnxHg1−xTe epitaxial films with x=0.12–0.19 in the wavelength range of 2–24 µm at 300 and 80 K were measured. The absorption caused by transitions of charge carriers between subbands of light and heavy holes is calculated according to Kane’s theory taking into account the effect of remote bands. The values of the effective masses of heavy and light holes are obtained as functions of solid-solution composition and temperature. The analysis of low-temperature absorption spectra was carried out; the ionization energy of the acceptor level is evaluated.
