    Scanning X-ray nanodiffraction: From the experimental approach towards spatially resolved scattering simulations
    (London : BioMed Central, 2012) Dubslaff, Martin; Hanke, Michael; Patommel, Jens; Hoppe, Robert; Schroer, Christian G.; Schöder, Sebastian; Burghammer, Manfred
    An enhancement on the method of X-ray diffraction simulations for applications using nanofocused hard X-ray beams is presented. We combine finite element method, kinematical scattering calculations, and a spot profile of the X-ray beam to simulate the diffraction of definite parts of semiconductor nanostructures. The spot profile could be acquired experimentally by X-ray ptychography. Simulation results are discussed and compared with corresponding X-ray nanodiffraction experiments on single SiGe dots and dot molecules.
