Structure and Optical Properties of Superlattices ZnO Doped with Mg

Article Preview

Abstract:

Based on the first-principles calculations, we present a study for Mg-doped superlattices ZnO. We find that the volume of superlattices ZnO is reduced, while the band gap is extended. The dielectric function peaks of superlattices ZnO become smaller in the low-energy region. Interestingly, we further find Superlattices ZnO has great geometrical stability due to the electrostatic potential of the doped layer is smaller than that of pure ZnO. The results provide a theoretical basis for photoelectric device manufacturing.
