Abstract
Direct interband magneto-optical transitions have been observed in pure -type InSb at liquid-helium temperature using magnetic fields up to 96.5 kG. The theory of the magnetic levels in the valence and conduction bands at the zone center is carried out using a modification of the method of Luttinger and Kohn. The interaction between conduction and valence bands has been treated exactly, and the effect of higher bands to order . Selection rules have been evaluated for both allowed () and warping-induced () direct valence-to-conduction-band transitions. Comparison of theoretical with experimental spectra (using circular and plane-polarized light in the Faraday and Voigt configurations, respectively) has shown good agreement for the magnetic field in the [110] and [100] crystal directions. The following band parameters are obtained: conduction-band effective mass : light-hole effective mass ; heavy-hole effective masses , , .
