Pressure-induced resonance broadening of exciton line shapes in semiconductors: Direct determination of intervalley scattering rates in GaAs
(American Physical Society, 1991)We show that the exciton photoluminescence line shape in the GaAs/AlxGa1-xAs quantum wells under pressure is broadened by hybridization of the Γ exciton with the X and the L continua via electron-phonon coupling. Furthermore, ...
