Web6 nov. 2016 · The resolution of an AFM is basically determined by how sharp the tip is, and with a tip that truncates with a single atom, one can have an atomic resolution. So the way these images are made is by scanning an extremely sharp tip across a surface and measuring at each point either the force exerted on the tip or the height of the surface. WebActually, it is. Atoms are made up of protons, neutrons, and electrons. However, if you remove any of these particles the atom will have different properties. An atom is the …
