Spontaneous emission mechanisms of GaInAsN/GaAs quantum dot systems
Variable-temperature photoluminescence(PL)spectra taken on two different kinds of GaInAsN quantum dots(QDs), having different In and N compositions and thicknesses, have been investigated both experimentally and theoretically. It is found that the temperature dependence of the spontaneous emissions from both samples behaves differently. Adopting a localized-state luminescence model, the quantitative reproduction of the measured variable-temperature PLspectra reveals a dissimilarity in...[Show more]
