Coherent Optical Spectroscopy of Electron Scattering in a Two Dimensional Electron Gas in High Magnetic Fields

Abstract

Coherent optical spectroscopy has emerged as an important experimental tool in the study of carrier dynamics in semiconductor quantum wells (QWs). Numerous studies of exciton dynamics have shown that the coherent nonlinear interaction in intrinsic QWs could be described in most cases by a simple two level system model. A more complex behavior is expected in modulation doped (MD) structures, where the interaction between the photo-excited electron-hole pairs and the two-dimensional electron gas (2DEG) is important.
