摘要
The polarization field in InGaN/AlInGaN quantum wells (QW) grown on GaN was investigated. The AlInGaN barrier was lattice-matched to the GaN substrate. A paraboliclike energy shift, an intensity minimum and an 180° phase change at the flat-band voltage was revealed by the bias-dependent spectra due to the quantum-confined Stark effect. The results show that the polarization field in the InGaN/AlInGaN QW is reduced significantly and is attributed to the contribution of spontaneous polarization in the quaternary barrier which compensates the piezoelectric polarization in the InGaN QWs.
