We present results of ab initio calculations of optical spectra of GaP and GaAs (110) surfaces, and show that transitions between bulk single-particle states modified by the crystal truncation account for the largest contribution to above-gap optical anisotropy of these systems.

Abstract
We present results of ab initio calculations of optical spectra of GaP and GaAs (110) surfaces, and show that transitions between bulk single-particle states modified by the crystal truncation account for the largest contribution to above-gap optical anisotropy of these systems.
