Piezoresponse Force Microscopy Mode


Piezoresponse Force Microscopy mode

Piezoresponse Force Microscopy mode (PFM) is a AFM contact mode. An electrical oscillation is applied to the conductive tip during scanning. Mapping piezoelectric orientation areas is carried out by measuring the amplitude of oscillation and the offsets of the phase signal.


 Material Science


Mapping piezoelectric field

Piezoresponsive materials are substances that undergo mechanical deformation in response to an applied voltage. Piezoresponse Force Microscopy (PFM) enables high-resolution nanoscale characterization of this piezoresponsive materials.
