NSLS-II Seminar

"X-ray Fluorescence Holography in Theory and Experiment"

Presented by Jainming Bai, University of Tennessee

Thursday, August 20, 2009, 10:00 am — NSLS-II Seminar Room, Bldg. 817

X-ray fluorescence holography is a new structure determination method developed in the last two decades. It can provide 3D atomic image around a fluorescence atom in a crystal structure and thus being considered as a promising tool for determination of local structures of doped atoms, buried clusters and impurities in a bulk crystal, as well as solving structures of nano-crystals, quasi-crystals or other structures lacking of long range translational order. The current state of the atomic resolution x-ray holography will be discussed with emphases on the near field effects and the recent XFH/MEXF measurements conducted at NSLS will be reported.
