Atomic force microscopy
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.

detection. As the cantilever is displaced via its interaction with the
surface, so too will the reflection of the laser beam be displaced
on the surface of the photodiode.

1.1

In some variations, electric potentials can also be scanned
using conducting cantilevers. In more advanced versions, currents can be passed through the tip to probe the
electrical conductivity or transport of the underlying surface, but this is much more challenging with few research
groups reporting consistent data (as of 2004).[1]
