Three-dimensional grain mapping by x-ray diffraction contrast tomography and the use of Friedel pairs in diffraction data analysis.
Wolfgang Ludwig,Péter Reischig,Andrew King,Michael Herbig,Erik Mejdal Lauridsen,G. Johnson,Thomas James Marrow,Jean-Yves Buffiere +7 more
TL;DR: A modified DCT data acquisition strategy is described which permits the incorporation of an innovative Friedel pair method for analyzing diffraction data, resulting in an increase in the accuracy with which the diffraction vectors are determined.
Experimental surface charge density of the Si (100)-2x1H surface
J. Ciston,Laurence D. Marks,Robert Feidenhans'l,Oliver Bunk,Gerald Falkenberg,Erik Mejdal Lauridsen +5 more
TL;DR: In this paper, a three-dimensional charge density refinement from x-ray diffraction intensities of the Si (100) 2x1H surface is reported, which is in remarkably good agreement with density-functional theory calculations.
Structure determination of the Si(001)-(2×1)-H reconstruction by surface X-ray diffraction: weakening of the dimer bond by the addition of hydrogen
Erik Mejdal Lauridsen,Jeff Baker,Mourits Nielsen,Robert Feidenhans'l,Gerald Falkenberg,Oliver Bunk,J. H. Zeysing,Robert L. Johnson +7 more
TL;DR: In this article, the atomic structure of the monohydride Si(001)-(2×1)-H reconstruction has been investigated by surface X-ray diffraction and the bond length of the hydrogenated silicon dimers was found to be 2.47±0.02

Mapping misoriented fibers using X-ray dark field tomography
TL;DR: In this article, a method for creating a dark field tomogram on a highly nonisotropic sample, i.e., a five layer "sandwich" of oriented carbon fibers, was proposed.

Malgorzata Makowska,Luise Theil Kuhn,Lars Nilausen Cleemann,Erik Mejdal Lauridsen,Hassina Z. Bilheux,Jamie J. Molaison,Louis J. Santodonato,Anton S. Tremsin,Mirco Grosse,M. Morgano,Saurabh Kabra,Markus Strobl +11 more
TL;DR: A new sample environment for in situ high resolution neutron imaging experiments at temperatures from room temperature up to 1100 °C and/or using controllable flow of reactive atmospheres and the possibility to directly combine imaging with diffraction measurements is presented.
