Wigner Crystallization in mesoscopic 2D electron systems
arXiv:cond-mat/0012265 · doi:10.1103/PhysRevLett.86.3851
Abstract
Wigner crystallization of electrons in a 2D quantum dots is reported. It proceeds in two stages: I) via radial ordering of electrons on shells and II) freezing of the inter-shell rotation. The phase boundary of the crystal is computed in the whole temperature--density plane, and the influence of quantum effects and of the particle number is analyzed.
