Abstract

The presence of strong magnetic fields significantly modifies electronic states of a semiconductor, such as quantization of energy levels (Landau levels) and shrinkage of exciton wave functions.1 Consequently, significant changes in optical as well as transport properties of the material are expected. In this paper, we report observations of an enhanced nonlinear optical response and a dramatic reduction of mobilities for magnetoexcitons in GaAs. We also discuss nonlinear optical measurements of excitons associated with higher Landau levels.
