Analytic S-Shaped Temperature Dependence of Peak Positions of the Localized-State Ensemble Luminescence and Application in the Analysis of Luminescence in Non- and Semi-Polar InGaN/GaN Quantum-Wells Micro-Array
Abstract:Two analytic expressions of temperature-dependent peak positions of localized-state ensemble (LSE) luminescence model are deduced for the cases of ΔE = E

0 > 0 and < 0, respectively, under the first-order approximation of Taylor’s expansion. Then, the deduced formulas were applied to examine the experimental variable-temperature photoluminescence data of non- and semi-polar InGaN/GaN quantum-wells (QWs) array by jointly co… Show more
