摘要：

In this work, an analytical expression for the complex dielectric function is proposed, which includes both discrete and continuum exciton effects. We have introduced Lorentzian broadening in Elliott's formula and compare our model to other models based on Elliott's formula. The results show that our model is superior to other models for the dielectric function of ZnO in the literature. Excellent agreement with experimental data for the dielectric function of ZnO for both perpendicular and parallel polarizations has been obtained using our model.
