In this review, after a brief discussion of Wigner’s ideas about the localization of electrons due to Coulomb interaction in a low-density electron system with neutralizing background and the formation of a periodic array, we present the various possibilities to realize Wigner crystals: on the surface of liquid helium, in semiconductor heterostructures, in graphene, in 1D systems and the analogous crystalline states in dusty plasma or in the assembly of trapped ions.
