Temperature dependent phase transitions of compounds (GeTe)(n)Sb(2)Te(3) (n = 6, 12, 15) have been investigated by in situ microfocus Laue diffraction. Diffusion processes involving cation defect ordering at ~300 °C lead to different nanostructures which are correlated to changes of the thermoelectric characteristics.
The experimental technique which has been of the greatest importance in revealing the structure of crystals is undoubtedly X-ray diffraction. The story of the discovery of X-ray diffraction in crystals by Laue,∗ Friedrich and Knipping in Munich in 1912 and the development of the technique by W. H. Bragg∗ andW. L. Bragg∗ in Leeds and Cambridge in the years preceding the First World War is well k...
The ever-increasing brightness of synchrotron radiation sources demands improved X-ray optics to utilise their capability for imaging and probing biological cells, nanodevices, and functional matter on the nanometer scale with chemical sensitivity. Here we demonstrate focusing a hard X-ray beam to an 8 nm focus using a volume zone plate (also referred to as a wedged multilayer Laue lens). This ...
An X-ray interferometer for high-resolution phase-contrast X-ray imaging was developed by thinning the central part of the analyzer crystal of a triple Laue-case (LLL) X-ray interferometer. The interferometer was tested at beamline 47XU at the SPring-8, and the improvement of the resolution of interference patterns was successfully observed for a plastic sphere of 1 mm diameter.
