We report on the effect of photogenerated free carriers on the spectral diffusion and on the LO-phonon Raman scattering of resonantly excited excitons. This is observed by an exciton population redistribution between localized states and by a decrease in the Raman scattering intensity under an extre

We report the use of intermixing techniques to modify GaAs/AlGaAs multiple quantum wells (MQWs). A large shift in the response wavelength of the GaAs/AlGaAs MQW-based infrared photodetector is obtained by proton implantation and then a standard annealing procedure (950 • C for 30 s). The photolumine
