Abstract
Direct interband magneto-optical transitions have been observed in bulk and epitaxial films of InAs with magnetic fields up to 100 kOe. The results are interpreted using a modification of the method of Luttinger and Kohn which includes the effects of nonparabolic conduction and light-hole bands, and warping of the conduction and valence bands. The following band parameters at k=0 are obtained for K: conduction-band effective mass ; light-hole effective mass ; and conduction-band factor . Further experimental results (obtained from magnetoabsorption data) are given for the energy dependence of the conduction-band factors in InSb and InAs. These are compared with the results computed theoretically.
