Symmetries in Piezoresponse Force Microscopy
The tremendous success of piezoresponse force microscopy (PFM) in various fields of material research has been driven by its promise to locally reconstruct the piezoelectric tensor and thus the polarization state by value and orientation. In order to achieve such a reconstruction, PFM generally allows for the collection of five different signals at once:topography, vertical amplitude, vertical phase, lateral amplitude, and lateral phase.
