摘要：

Piezoresponse force microscopy (PFM) is used to measure the effective piezoelectric coefficient (d(33)) of an individual (0001) surface dominated zinc oxide nanobelt lying on a conductive surface. Based on references of bulk (0001) ZnO and x-cut quartz, the effective piezoelectric coefficient d(33) of ZnO nanobelt is found to be frequency dependent and varies from 14.3 pm/V to 26.7 pm/V, which is much larger than that of the bulk (0001) ZnO of 9.93 pm/V. The results support the application of ZnO nanobelts as nanosensors and nanoactuators.
