Theory of Surface Optical Properties
Theory of Surface Optical Properties
The theory of surface optical properties is reviewed. The use of Many-Body Perturbation Theory, with Density Functional Theory calculations as zero order approximation, is now the state of the art to obtain quasi-particle excitation energies and optical spectra of surfaces. In this paper we will present the current status of theoretical and computational approach. Realistic calculations of surface optical properties within the single-particle approximation and within the ManyBody Perturbation Theory are discussed; as examples, results for InAs(110) and C(100) surfaces are given. © Springer-Verlag Berlin Heidelberg 2005.
