| Abstract(in English) | Accurate measurement of internal quantum efficiency (IQE) is necessary for a comprehensive understanding of the electronic structures and carrier dynamics in InGaN quantum-well emitting layers, and we have proposed simultaneous photoacoustic (PA) and photoluminescence (PL) measurements for such accurate IQE estimation. In this study, we have performed line-scan measurements of the simultaneous PA and PL measurements for InGaN quantum wells on a stripe-core GaN substrate, where the defect density spatially varies significantly. The results show that the PA and PL signal intensities show complemental relationship, which is quite reasonable. However, the data are affected by substrate absorption of the excitation light, and such effects should be removed to estimate accurate IQE values from the measurement data |
