The influence of a continuum background on photoluminescence of self-assembled InAlAs/AlGaAs quantum dots

We have investigated the effect of the low energy tail of the continuum states associated with wetting layers (WL tail) on temperature dependence of the photoluminescence (PL) spectra of self-assembled InAlAs/AlGaAs quantum dots. We have developed a model that studies this effect. The results of thi...
