Schematic illustration of Friction Force Microscopy (FFM). The AFM cantilever, a small diving board-like structure about 200 micrometers long, 50 micrometers wide, and 1 micrometer thick, has a sharp ...
AFM is particularly well-suited to working with soft materials in the field of nanomechanical measurements, owing to its piconewton force resolution and sub-nanometer vertical displacement accuracy.
