摘要：

Here we present first measurements of the local piezoelectric activity of thin vinylidene fluoridetrifluoroethylene (VDF-TrFE) copolymer films with a spatial resolution of about 10 nm. The average value of the piezoelectric constant d33 is - 0.03 nm/V verying typically by about 20% across a distance of 10 nm depending on the poling state of the film.
