Phys. Rev. Lett. 99, 256401 (2007) [4 pages]Long-Range Order in Quasi-One-Dimensional ConductorsReceived 29 December 2006; published 17 December 2007 We study the formation of the charge-density wave long-range order in a system of repulsive 1D electrons coupled to 3D phonons. We show that the charge-density wave can be stabilized by interaction with phonons in quasi-1D crystals and semiconducting nanowires. In the case of metallic atomic chains, interaction with phonons of a 3D substrate is not enough, and violation of the translational invariance by commensurable perturbation or disorder is needed. The possibility of stabilization of superconductivity in 1D electrons with attraction by means of tunnel coupling to a 3D metal is considered. © 2007 The American Physical Society URL:
