ABSTRACT
The grain boundary (GB) of nanocrystalline ZnO films is investigated using the x-ray absorption fine structure technique. With the advantage of the dominant GB volume fraction in our samples, the GB structure is found to be neither simply “gas-like” nor “similar to that of coarse-grained phase,” but experiences a transition from the modestly ordered innermost coordination shell around centered atoms to partly disordered second coordination shell and then to completely disordered higher coordination shells. © 2004 American Institute of Physics.

    Aberrations of rays reflected in a Cauchois scheme are considered on the basis of geometrical concepts of propagation of X-rays. It is shown that geometrical aberration can exceed the Borman delta width as well as the diffraction width of the focus. To reduce the influence of aberrations, the...

    The development effort is driven by the need for a new type of x-ray beam position monitor (XBPM), which will detect the centre of gravity of the undulator beam. XBPMs based on the ionization of a residual gas are considered being the candidate for this future “white” undulator beam...

    The properties of OH megamaser galaxies in the x-ray and radio ranges are discussed. Based on a sample of OH megamaser galaxies it is shown that the x-ray emission and the width of the OH radio line are closely related. The line width is also related to the radio emission from megamasers, but it...
