X-ray topographic determination of the granular structure in a graphite mosaic crystal: a three-dimensional reconstruction

Section topographs recorded at different spatial locations and at different rocking angles of a highly oriented pyrolytic graphite crystal allow three-dimensional maps of the local angular-dependent scattering power to be obtained. The maps allow the extraction of information on local structural parameters such as size, form and internal mosaic spread of crystalline domains, and represent a new approach to the characterization of mosaic crystals.
