Experimental and simulated I - V curves. (a) I-V characteristics for the ZnO wire-gold junctions obtained experimentally (empty circles), in comparison with the simulated curves, where ZnO is either placed on the gold electrodes (straight line) or between them (dot line). Atomistix toolkit (ATK) scheme of ZnO between the gold electrodes (b, top view) or on them (c, lateral view). (d) Experimental and (e) simulated I-V of the ZnO-gold junction (black line) and of ZnO-NH2-gold one (red line).
