Pseudopotential Calculation of the Optical Constants of MgO from 7-28 eV

Abstract

The electronic band structure of MgO is computed using the empirical pseudopotential method. The resulting energy bands are then used to calculate the optical constants over a wide range in energy. The optical constants calculated are the real and imaginary parts of the dielectric function, the reflectivity, and the imaginary part of the inverse dielectric function. Optical interband transitions are identified, and a comparison between experiment and theory is made.
