Low-temperature growth of (2 1¯1¯ 0) ZnO nanofilm on NaCl (0 0 1) surface by ion beam sputtering

ZnO nanofilm of the (2 1¯1¯ 0) surface was prepared by ion beam sputtering deposition. The nanofilm was prepared on NaCl (0 0 1) surface at 200 °C to produce nearly pure (2 1¯1¯ 0)ZnO texture and the orientation relationship was determined and the interface discussed. Transmission electron microscopy lattice images were used to find the interface formed between ZnO nanocrystals. The ZnO nanocrystals coalesced to form a straight (0 1¯1¯ 2) interface. The photoluminescence spectrum from the (2 1¯1¯ 0)ZnO surface showed only a near-band-edge UV emission peak.
