We study a model that describes Wigner crystallization of electrons in low-dimensional solids. Restricting the electron motion into layers or chains, while keeping the full three-dimensional nature of the Coulomb interactions, can result in a sizeable stabilization of the crystallized phase as compared to the usual three-dimensional case. A sequence of structural transitions of the electron crystal is also predicted upon varying the density.

Abstract
We study a model that describes Wigner crystallization of electrons in low-dimensional solids. Restricting the electron motion into layers or chains, while keeping the full three-dimensional nature of the Coulomb interactions, can result in a sizeable stabilization of the crystallized phase as compared to the usual three-dimensional case. A sequence of structural transitions of the electron crystal is also predicted upon varying the density.File in questo prodotto:
