ZnOfilmswith thickness of 80 nmwere grownbypulsed laser deposition (PLD) onMgO (100) single crystal and amorphous fused silica (FS) substrates. Structural studies of ZnO films and a high quality reference ZnOsingle crystalwereperformedby slowpositron implantation spectroscopy (SPIS). Itwas found that ZnO films exhibit significantly higher density of defects than the reference ZnO crystal. Moreo...
ZnO thin films deposited on various substrates were characterized by slow positron implantation spectroscopy (SPIS) combined with X-ray diffraction (XRD). All films studied exhibit wurtzite structure and crystallite size 20-100 nm. The mosaic spread of crystallites is relatively small for the films grown on single crystalline substrates while it is substantial for the film grown on amorphous su...

Abstract The importance of constructing sub-national spatial price indexes (SPIs) has been acknowledged in the literature for over two decades. However, systematic attempts to compile SPIs on a regular basis have hampered by labour-intensive analyses required processing traditional data. In case household consumption expenditures, increasing availability big data may change current approach est...
