摘要
We examine how the short-range part of the electron-hole exchange interaction influences the strain-induced variations of the oscillator strength in ZnO films. Our model enables us to account for the surprisingly small oscillator strength of the A exciton in E perpendicular to c polarization without having to invoke any inverted valence-band scheme. We then conclude that the valence-band physics is very similar in both ZnO and GaN.
