WebThese materials can be characterized using Piezoresponse Force Microscopy (PFM), a variant of contact mode AFM. Typically, an AC voltage is applied to the tip and the resulting nanoscale deformation is measured. This deformation stems from the strain generated by the application of an external electric field (inverse piezoelectric effect). WebPrinciple of photonic force OCE Inspired by the pioneering work of Nobel laureate Arthur Ashkin35, we exploited a less conventional mode of optical manipulation, based on radiation pressure from a low-NA beam, to develop photonic force (PF)-OCE for 3D mechanical microscopy36. PF-OCE utilizes radiation pressure from a low-NA beam (NA ≤ 0.4 ...
