Abstract

Temperature dependencies of photoluminescence (PL) characteristics of an MBE and an MOCVD grown InGaN/GaN multiple quantum well samples of similar structure and composition were compared. Based on the calculations of PL mean wavelength and root-mean-square spectral width, we observed the differences in their photon emission characteristics. Although both of them showed S-shape variations in mean wavelength, their values are quite different in spite of the similar structure and composition. Meanwhile, the MBE sample showed a unique two-component decay in the PL integrated intensity. The possible mechanisms behind these phenomena are also discussed in this paper.
