Abstract

We report on cyclotron resonance (CR) experiments of high-quality C-doped two-dimensional hole systems in GaAs/AlGaAs quantum wells covering the microwave and far-infrared regimes. At high magnetic field B we observe a strong B dependence of the cyclotron mass mc which can be reproduced by calculations based on a 4×4 Luttinger Hamiltonian in the axial approximation. At small B one main and up to ...
