title = "The stress-dependent piezoelectric coefficient of ZnO wire measured by piezoresponse force microscopy",
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.",
