Growth and Electrical Properties of Zinc Oxide Nanowires
Zinc oxide nanowires were grown on molybdenum grids with a simple chemical vapor transport and deposition method through thermal evaporation of zinc powder at a temperature of 600 °C. These nanowires are 20∼50 nm in diameter and over ten microns in length. High resolution transmission electron microscopy studies show that the as-grown nanowires are single crystal of wurtzite structure and grow along the 〈0001〉 direction. The growth process was explained with a vapor-solid mechanism under zinc-rich conditions. We further patterned electrodes on individual ZnO nanowires by e-beam lithography and studied thier electrical properties.
