Abstract : We used the Scanning Nearfield Acoustic Microscope a nontouching profilometer with a conducting tip - both to pole thin ferroelectric VDF-TrFE copolymer films and to subsequently monitor the resulting piezoelectrically stimulated surface motion. For thin uncovered polymer films we were able to measure simultaneously the piezoactivity and the surface topography with a lateral resolution of 1 micron m. Furthermore we used a focused electron beam to create a poling pattern of narrow lateral extension and detected the corresponding local piezoactivity by using the Scanning Nearfield Acoustic Microscope.
