Optical properties of the cleavage InAs(110) surface

摘要

The electronic and optical properties of the cleavage InAs(110) surface are studied using a semi-empirical tight-binding method which employs an extended atomic-like basis set. We calculate the surface electronic band structure and the Reflectance Anisotropy Spectrum. We describe and discuss the optical properties in terms of the surface electronic states and we compare our results with other theoretical approaches, and with experimental observations.
