Av. Gopal et al., Photoluminescence study of exciton-optical phonon scattering in bulk GaAs and GaAs quantum wells, J APPL PHYS, 87(4), 2000, pp. 1858-1862
We obtain the temperature dependence of the homogeneous linewidth of excito
ns in GaAs quantum wells (QWs) and bulk GaAs using photoluminescence measur
ements. The results indicate that exciton scattering rates with optical pho
nons are larger in bulk GaAs than in QWs. (C) 2000 American Institute of Ph
