Abstract

Array growth of small-diameter (10–15 nm) zinc oxide (ZnO) nanowires by patterning and template-directed growth methods is reported. The ZnO nanowire arrays (see Figure) were patterned over large areas (∼1 cm2), and exhibited photoluminescence—a characteristic of highly crystalline materials.
