Bragg diffraction imaging enables the quality of synthetic single-crystal diamond substrates and their overgrown, mostly doped, diamond layers to be characterized. This is very important for improving diamond-based devices produced for X-ray optics a

Contrast in transmission X-ray diffraction topographs of growth defects in the core of SrLaGaO4single crystals

Autor: M. Lefeld-Sosnowska, Jürgen Härtwig, A. Malinowska

Publikováno v: Journal of Applied Crystallography. 46:48-54

Defects in the core of SrLaGaO4single crystals, grown by the Czochralski method using a [001]-oriented seed, were studied by transmission X-ray diffraction projection topography. Topographs were taken with radiation from a laboratory source and with
