Photoluminescence kinetics of multiperiod GaAs/AlGaAs structures with asymmetric barriers promising for making unipolar lasers

Photoluminescence kinetics in multiperiod GaAs/AlGaAs quantum-well structures with asymmetric barrier heights has been investigated. Owing to the barrier asymmetry, a time constant of nonradiative recombination between the laser subbands of 9 ps has been achieved, which is record long for unipolar l...
