Smaalen, Sander van - University of Bayreuth - Laboratory of Crystallography

研究领域

Research at the laboratory of crystallography aims at establishing relationships between crystal structure and physical properties, as well as at providing the structural basics for the understanding of phase transitions. The Research is concentrated on aperiodic crystals, including phase transitions between incommensurate, periodic and partially ordered structures. The second topic of interest is accurate charge-density studies by the Maximum Entropy Method for both periodic and aperiodic crystals. Experimental methods at the Laboratory of Crystallography include single-crystal x-ray diffraction and x-ray powder diffraction (Equipment). Both techniques can be combined with low- and high temperature attachments and they can be performed at high pressures. X-ray scattering is also performed with synchrotron radiation at Hasylab (Hamburg), ESRF (Grenoble), and NSLS (Brookhaven - USA).
