potential well Line breaks: po¦ten|tial well

Entry from British & World English dictionary

Definition of potential well in English:


A region in a field of force, in particular the region in which an atomic nucleus is situated, in which the potential is significantly lower than at points immediately outside it, so that a particle in it is likely to remain there unless it gains a relatively large amount of energy.
Example sentences
  • This lattice can trap the neutral atoms in potential wells because the electric fields of the lasers induce a dipole moment in the atom.
  • Then, by applying an electric field perpendicular to these layers, you create a potential well which can confine electrons along this perpendicular direction.
  • The defects produce a potential well which holds the electrons in them.
