(Color online) (a) FESEM image of as-grown ZnO NWs. (b) TEM image of a cross section of a single ZnO NW. (c) High-resolution TEM image of an as-grown ZnO NW with lattice spacing, growth direction, and outermost surface layer, as indicated. The inset shows a TEM image of crystalline structure at a boundary surface of a ZnO NW. (d) A schematic diagram illustrating our two-contact ZnO NW devices.
(Color online) (a) Temperature dependent curves of a ZnO NW device with a low RT resistance of . The temperature range is from 300 (steepest curve) to (flattest curve). curves in wider voltage range are plotted in the inset. (b) Resistance of the NW device as a function of inverse temperature.
(Color online) (a) curves of a ZnO NW device with a high RT resistance of . Inset: as a function of inverse temperature. (b) Resistance of the NW device as a function of . The inset schematically depicts the contact between Ti electrode and ZnO NW.
