title = "Polarity determination of wurtzite-type crystals using hard x-ray photoelectron diffraction",
abstract = "The surface structure of a single-crystal ZnO wafer was studied by angle-resolved x-ray photoelectron spectroscopy (ARXPS) using synchrotron radiation. As a result, well-defined x-ray photoelectron diffraction (XPD) patterns were obtained for the (0001) and (000{\=1}) polar surfaces using the photoemission from the Zn 2p3/2 and O 1s core levels. The XPD patterns were indexed assuming forward scattering of photoelectrons by neighboring ions. Further, the XPD patterns for the (0001) and (000{\=1}) surfaces were different from each other, indicating the possibility for using the XPD technique for polarity determination.",
