Abstract

Two concepts of X‐ray diffuse scattering holography resulting in local atomic structure are presented. The first one uses the anomalous scattering near the absorption edge of a selected element. The second one is based on the variation of atomic scattering factor due to the isomorphous replacement of a selected atom in the structure by another one with different scattering properties. Feasibility of both concepts was demonstrated experimentally on a RbCl single crystal and GaMnAs epitaxial layer. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
