Abstract

The effects of anisotropy of the valence-band structure and of the mixing of the heavy and light holes on the Landau levels of the hole inversion layer in a normal magnetic field are studied. Some of the crossings of the Landau levels which occur when anisotropy is neglected are removed when it is included. While the measured multiple cyclotron-resonance frequencies are explained qualitatively by our calculation, there is quantitative disagreement.
