Noncontact atomic force microscopy ncafm, also known as dynamic force microscopy dfm, is a mode of atomic force microscopy, which itself is a type of scanning probe microscopy. In the contact mode, the afm tip scans across a surface at a very low force and is deflected by the repulsive force between the tip and surface atoms. Unlike traditional microscopes, the afm does not rely on electromagnetic radiation, such as. There are two primary modes of operation for an atomic force microscope, namely contact mode and noncontact mode depending on whether the cantilever vibrates during the operation.
