Abstract
Optical pump-probe experiments on bulk GaAs and conventional type I GaAs/GaAlAs multiquantum well structures (MQWSs) have determined the time scales on which photoexcited carriers (1) attain thermal equilibrium among themselves, (2) scatter out of the zone-center Γ valley to accessible X or L valleys, (3) relax their excess energy to the lattice, and (4) recombine.1-3
