Piezoresponse Force Microscopy Mode

Overview

PFM principle

PFM principle

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
