Piezoresponce Force Microscopy (PFM) is an AFM mode which probes the mechanical deformation of a sample in response to an electric field which is applied between tip and sample. It allows to visualize ferroelectric domains, perform direct measurement of piezoelectric coefficients, study the dynamics of domain walls, etc. with high spatial resolution. These studies are essential for understanding the nature of new functional materials and devices for optoelectronics, data storage, medical diagnostics, actuators, etc.
