Local Fatigue Evaluation in PZT Thin Films with Nanoparticles by Piezoresponse Force Microscopy
Figure 4
Piezoelectric histograms of three kinds of PZT films. Three types of histograms about virginal film, during fatigue and after fatigue, are shown, respectively, in (a) PZT, (b) PZT-BT1, and (c) PZT-BT5 films.
