Abstract
Cyclotron resonance has been observed in the two-dimensional (2D) hole gas found in selectively doped heterostructures and multiple quantum wells, in magnetic fields up to 20 T. The results are compared with recent theories as well as a simple model of the 2D hole band structure obtained by taking a section through the three-dimensional valence band at a finite wave vector along the growth direction. Only rough quantitative agreement is achieved.Keywords
