Exciton Relaxation and Quantum Mechanical Level Repulsion

Abstract

Theoretical results for spatially resolved exciton spectra of quantum wells with disorder are discussed. As a consequence Of quantum mechanical level repulsion the autocorrelation of the sharp peaks corresponding to individual quantum states yields information on their spatial extent. Level repulsion is present not only in the density of states but as well in absorption and even luminescence. More generally the question under what conditions level repulsion can be observed in disordered systems with localized states is addressed.
