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.
