摘要
We present the GW band structure of ZnO in its wurtzite (WZ), zincblende (ZB) and rocksalt (RS) phases at the Gamma point, calculated within the GW approximation. We have used a Zn(20+) pseudopotential which is essential for the adequate treatment of the exchange interaction in the self-energy. The accuracy of the pseudopotential used is also discussed. The effect of the p-d hybridization on the GW corrections to the band gap is correlated by comparing the ZB and RS phase.
