This investigation describes the growth of sparsely dispersed vertical ZnO nanowires on sputtered-ZnO:Ga/sapphire templates by self-catalyzed vapor liquid solid method. Experimental results indicate that these ZnO nanowires grew with the preferred (002) orientation with good crystal quality. Conductive diamond-coated point probe forms Schottky contact on single ZnO nanowire with a sharp turn-on voltage of ∼2.5 V and a barrier height of approximately 0.38 eV.
