Spontaneous emission mechanisms of GaInAsN/GaAs quantum dot systems

Wei, Z. F.; Xu, S. J.; Li, Q.

Description

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]
