Method

Atomic force microscopy (AFM) or scanning force microscopy (SFM) uses a sharp tip as a sensor to measure forces between the sample and the tip. The tip is attached to a soft cantilever. The cantilever is bent when a force acts on the tip and this bending is quantified by the deflection of a laser beam reflected at the backside of the cantilever. The tip moves over the sample during which different forces act between sample and tip. The image data can be transformed to a false-color image for display. Different forces can be utilized for image generation which opens opportunities to image different materials properties.
