摘要：

Large spectral red shifting (similar to140 meV) and reduced radiative recombination efficiency are observed on the high excitation luminescence spectra of InGaN/GaN quantum wells capped with a AlGaN top barrier compared with that of a GaN cap layer. These observations are ascribed to the additive internal field effect due to the spontaneous polarization induced volume charge at the AlGaN/InGaN interface.
