Dependence on temperature of circular polarization and relaxation time in InAlAs/AlGaAs quantum dots

Résumé

We have studied the variation of photoluminescence circular polarization as a function of temperature in self-organized InAlAs/AlGaAs quantum dots. We have found that the circular polarization depends on temperature. The relaxation time tau(s) is deduced from the circular polarization degree. It decreases from 2 ns at 40 K to 100 ps at 85 K.
