MOCVD growth and fabrication of group-Ill nitrides for high-efficiency MQW LEDs

Abstract

bandgap energy of the electroluminescence peak and anomalous temperature shift) we developed a model in which we assume that the radiative transitions involve Gaussian-like tails of conduction and valence bands. The model can account for temperature dependence of light intensity and emission peak position, and for temperature insensitivity of emission bandwidth. The emission peak position can be expressed in this approach as:
