Time-resolved exciton dynamics and stimulated emission from ZnCdSe/ZnSe multiple quantum well structures

Abstract:

Time-resolved luminescence has been used to investigate the dynamics of excitonic recombination and stimulated emission in ZnCdSe/ZnSe multiple quantum wells where the exciton binding energy is close to the optical phonon energy. At low excitation densities strong excitonic recombination is observed with simple exponential decay kinetics. At densities near threshold, however, bilinear recombination kinetics are found with a large rate constant (R = 1.8 × 10-3 S-1 cm2), and a dramatic reductio...
