Ultrafast Magnetoexciton Dynamics in GaAs

Abstract

A bulk semiconductor provides an excellent system for optically studying the ultrafast dynamics of Coulomb correlated magnetoexcitons. The application of a magnetic field to a 3-D system quantizes the energy levels of states with momentum perpendicular to B and, in contradistinction to experiments performed on 2-D quantum well systems, leaves a 1-D continuum of states with momentum parallel to B. The presence of the continuum states has a dramatic influence on both the linear and nonlinear optical properties. Thus, the experiments described below track the evolution of the semiconductor from a 3-D to a 1-D system and reveal surprising optical properties not observed in the previously reported studies in quantum wells.
