Atomic force microscopy - Wikipedia
Atomic force microscopy (AFM) or scanning force microscopy (SFM) is a very-high-resolution type of scanning probe microscopy (SPM), with demonstrated resolution on the order of fractions of a nanometer, more than 1000 times better than the optical diffraction limit.

9.2: Atomic Force Microscopy (AFM) - Chemistry LibreTexts
Aug 28, 2022 · Atomic force microscopy (AFM) is a high-resolution form of scanning probe microscopy, also known as scanning force microscopy (SFM). The instrument uses a cantilever with a sharp tip at the end to scan over the sample surface (Figure 9.2.1 9.2. 1).
Phys. Rev. Lett. 56, 930 (1986) - Atomic Force Microscope
Mar 3, 1986 · The atomic force microscope is a combination of the principles of the scanning tunneling microscope and the stylus profilometer. It incorporates a probe that does not damage the surface. Our preliminary results in air demonstrate a lateral resolution of 30 ÅA and a vertical resolution less than 1 Å.
