Energy spectrum and optical absorption in p-CdGeAs2

In the Kein four-band model, taking account of interaction with excited bands, the energy spectrum and effective masses of electrons and holes in CdGeAs₂ are calculated. The polarizational dependence of the optical absorption spectrum is investigated for transitions between bands of light and heavy holes. The results are compared with experimental data.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 1, pp. 68–72, January, 1982.
