WebMay 31, 2005 · The atomic force microscope (AFM) is the most commonly used of the scanning probe family, due in part to its ease of use and versatility. The AFM produces a three dimensional image of a surface by scanning an atomically sharp tip, typically made from etched silicon, across a surface. The tip is attached to a cantilever which deflects as … WebMay 4, 2024 · STM - is the tunnelling current between a metallic tip and a conducting substrate which are in very close proximity but not actually in physical contact. AFM - is the van der Waals force between the tip and the surface; this may be either the short range repulsive force (in contact-mode) or the longer range attractive force (in non-contact mode).
