An AFM cantilever with a protruding ultra-sharp tip is raster scanned over the sample, which makes either intermittent or constant contact with the surface. The tip interacts with the sample, experiencing repulsive or attractive inter-atomic forces. A laser beam is reflected off the back of the cantilever onto a detector.
