Optical response spectra of surfaces and interfaces

Abstract

Recent status of optical response spectra calculations is reviewed, illustrating various bulk, surface, and interface systems. One can obtain fruitful information on atomic and electronic structures using the freedom of light such as energy (wave length) and polarization. Moreover, by explaining the spectral shape origin in refiectance diŠerence spectroscopy, we show that the optical response of surface and interface has quite diŠerent features and needs diŠerent calculation methods from those of bulk systems, refiecting the breakdown of translational symmetry.
