Abstract

We study the optical properties of the nonpolar (110) surface of cubic Boron Nitride calculated within the first-pinciple DFT-LDA scheme. The reflectance anisotropy (RA) spectrum is analyzed in relation to the better known spectrum of the GaAs(110) surface. The influence of the ionicity on the surface relaxation, the surface states character and the surface optical spectra, is studied. Comparisons with existing data for the surface under study and results to the GaN(110) surface are also given.
