Jh. Chu et al., TEMPERATURE AND DENSITY-DEPENDENCE OF EXCITON LIFETIMES IN GAAS ALGAAS MULTIPLE-QUANTUM WELLS, Optical and quantum electronics, 27(5), 1995, pp. 387-393
The photoluminescence linewidths and exciton lifetimes of free exciton
s in GaAs/AlGaAs multiple quantum wells were systematically investigat
ed as a function of temperature, quantum well width, and carrier densi
ty. The experimental results showed that the exciton decay processes w
ere strongly related to the linewidth of the exciton and the exciton b
inding energy.
