TL;DR: In this article, the structure of the polar surfaces of ZnO was studied using ab initio calculations and surface x-ray diffraction and the experimental and theoretical relaxations were in good agreement.

TL;DR: In this article, surface x-ray diffraction has been used to determine the structural relaxations of the titanium planes, and the results of three independent calculations of the energy minimization structure were compared with the positions of the predicted positions of titanium atoms predicted by Ramamoorthy et al.

TL;DR: The structures of the polar surfaces of ZnO are studied using ab initio calculations and surface x-ray diffraction and are shown to be very stable, leading to 2D metallic surface states, which has implications for the use of the material in gas sensing and catalytic applications.

TL;DR: The Nanoscience beamline (I06) as discussed by the authors is one of seven Diamond Phase I beamlines which has been operational since January 2007 delivering polarised soft x-rays, for a PhotoEmission Electron Microscope (PEEM) and branchline, in the energy range 80-2100 eV.

TL;DR: X-ray diffraction measurements have been made in real time during the deposition of the rare earth Sm on the non-alloying substrate Mo(110) as discussed by the authors, and the variation of the specularly reflected X-ray intensity with deposition time is consistent with the completion of a trivalent monolayer with an atomic density of 96% of a (0001) layer in bulk Sm.
