Abstract
Here we present first measurements of the local piezoelectric activity of thin vinylidene fluoride‐trifluoroethylene (VDF‐TrFE) copolymerfilms with a spatial resolution of about 10 nm. The average value of the piezoelectric constantd 33 is −0.03 nm/V varying typically by about 20% across a distance of 10 nm depending on the poling state of the film.Keywords
