We have investigated the surface structures and the local polarized domains of the copolymer thin films of vinylidene flouride and trifluoroethylene (P(VDF/TrFE)) by atomic force microscopy (AFM). AFM observation revealed that the films consisted of "rod-like" that the surface morphology depended strongly on the annealing condition. We also observed that pairs of "rod-like" grains were gradually formed depending on the length of the annealing time. The local polarized domains were fabricated by applying a high electric field to the film with a conducting AFM tip. The piezoelectric response of the film was detected using the tip with an oscillating electric field and imaged with the topographic images taken simultaneously. The X-ray profile suggested that the thin films had a β-type crystalline structure.
