Abstract

Optical transitions of 2-D excitons are believed to represent a typical model for inhomogeneous line broadening due to the well width fluctuations of the quantum wells.1 Because of the inhomogeneous broadening and its specified relaxation processes (relaxation of delocalized excitons to localized states), it is difficult to obtain information on the intrinsic relaxation times of delocalized excitons in such multiple-quantum-well structures.
