How quantum confinement can be obtained?

  1. Sep 24, 2015 #1

    I have been reading about quantum confined systems. That is, systems of 1 or 2 particles or atoms inside a region of space of radius R where potential energy is, say V(r), for r < R and infinity of r >= R. However, something I cannot find using Google is how one can obtain such space. I mean, if I can isolate two atoms, how can I put these two atoms inside a confined region?

    Those infinite potentials don't exist in the real world. Sometimes they are a good approximation, however. Electrons in a metal, for example, the surface of the metal has a very high potential step.
