Comparative Study of the Surface Roughness by AFM and GIXR
Abstract
The comparative analysis of surface roughness determined by using two complementary methods, the grazing incidence X-ray reflectometry (GIXR) and the atomic force microscopy (AFM), is presented. The (100) surfaces of different GaAs single crystals grown by the Czochralski method were investigated. The experimental X-ray data were compared with computer simulations basing on the Fresnel theory.
