Abstract
We studied a converse piezoelectric effect of individual ZnO wires by using a conductive cantilever tip attached to the end of each wire. The piezoelectric coefficients d33 of individual wires were measured and found to be in the range of 1–45 pm V−1, some of them being much larger than that of bulk ZnO. A 20% increment of d33 was found when 0.32 GPa stress was applied, but the d33 was decreased when the wire was bent by excessive compression.
