In HD Piezoresponse Force Microscopy mode (HD PFM) an AC voltage is applied to the conductive AFM cantilever when the tip comes in contact with the sample during each fast force spectroscopy cycle. Applied AC voltage causes mechanical oscillations of the piezoelectric (ferroelectric) sample.Corresponding vertical and lateral motions of the AFM tip are recorded and processed to get the amplitude and phase characterizing the local piezoelectric coefficient and local polarization direction respectively. Since the AFM tip retracts from the surface in each scanning point, the lateral tipsample interaction force is significantly reduced in comparison to the conventional contact PFM technique. This provides new capabilities for piezoresponse studies of soft, loose and fragile objects like biological samples, nanoparticles etc. Furthermore an AFM cantilever of higher stiffness and resonance frequency can be used.

Electrical characterization of objects, that are weakly attached to the surface, has always been a challenge when using standard AFM modes like Conductive AFM. This was because often the tip moved or abraded the objects of interest. HybriD Mode drastically decreased the impact of lateral forces and simplified these experiments. Comparison of conductive and mechanical maps shown in this example allows the clear identification of single nanotubes and bundles.
