Abstract :Rface and interface information. RAS measures the difference in reflectance of light eflectance anisotropy spectroscopy RAS is an optical technique to produce surlinearly polarised along two orthogonal axes in the surface at near normal incidence as a function of photon energy. The quantity obtained by RAS is the so-called reflectance anisotropy. Since only the surface is anisotropic, the measured reflectance anisotropy is connected only with the atomic composition of the surface, not of the bulk. This review presents theoretical as well as experimental procedure to explain RAS technique.Keywords : Reflectance anisotropy spectroscopy, Optical technique, Anisotropy, Polarized light
