Abstract
We present a new method for studying the electronic states of crystals in a magnetic field which enables us to calculate the Landau level en ergies and wavefunctions microscopically. The method is applied to bul k GaAs and a GaAs/AlGaAs short-period superlattice. The results explic itly show the effects of non-parabolicity, anisotropy and state-mixing s on both Landau level spectra and wavefunctions.
