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.
