WebInteracting forces. With AFM, one can measure the force between atoms at the tip and the sample which are located as close as 0.1–100 nm. The forces can be classified into attractive and repulsive forces. For attractive forces, van derWaals (vdW) interaction, electrostatic force and chemical force are included. WebThe atomic force microscope (AFM) is one kind of scanning probe microscopes (SPM). SPMs are designed to measure local properties, such as height, friction, magnetism, with a probe. To acquire an image, the SPM raster-scans the probe over a small area of the sample, measuring the local property simultaneously.
