| Abstract | The objective of this work is an evaluation of quantitative measurements of piezoresponse force microscopy for nanoscale characterization of ferroelectric films. To this end, we investigate how the piezoresponse phase difference ΔΦ between c domains depends on the frequency ω of the applied ac field much lower than the cantilever first resonance frequency. The main specimen under study was a 102nm thick film of Pb(Zr0.2Ti0.8)O3. For the sake of comparison, a 100nm thick PbTiO3 film was also used. From our measurements, we conclude a frequency dependent behavior ΔΦ∼ω−1, which can only be partially explained by the presence of adsorbates on the surface. |
