Abstract

We present calculations of hole Landau levels, cyclotron masses, and far-infrared spectra for strained asymmetric p-type Ge-Si$_{x}$Ge$_{1-x}$ quantum wells in a perpendicular magnetic field in order to interpret recent experimental results by Engelhardt et al. [Solid State Electron. 37, 949 (1994)]. Self-consistent hole subband calculations are combined with calculations of the Landau levels ...
