Abstract(in English) | Analysis of S-shaped temperature dependence of PL peak energy is widely used to evaluate the degree of compositional fluctuation in InGaN alloy materials used as active layers in LEDs and laser diodes. However, the fitting function commonly used in this analysis is derived on the basis of some bold approximation, and the analysis can be applied in only limited conditions (e.g. high temperature and small carrier density). In this work, we have established a new theoretical model which can be applied in wide ranges of temperature and carrier density. A measured S-shape behavior in an InGaN quantum-well structure has been analyzed by the theoretical model, and it is shown that the S-shaped behavior can be well fitted by our model in a wide temperature range, compared with the conventional model. |
