Ziegler" ], "comment": "4 pages, 3 figures", "categories": [ "cond-mat.mes-hall" ], "abstract": "A two-dimensional gas of non-interacting quasiparticles in a nearly periodic potential is considered at zero temperature. The potential is a superposition of a periodic potential, induced by the charge density wave of a Wigner crystal, and a weak random potential due to disorder. There is a metal-insulator transition that is controlled by the strength of the periodic potential. The transition is continuous in the presence of randomness. We evaluate the density of states, which is non-zero at the Fermi energy in the metallic phase, and the dc conductivity. The latter changes with decreasing modulation of the periodic potential from 0 to $\\sigma\\approx2e^2/h$.", "revisions": [ { "version": "v1", "updated": "2002-06-20T22:29:12.000Z" } ], "analyses": { "keywords": [ "periodic potential", "metal-insulator transition", "dimensions", "charge density wave", "weak random potential" ], "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2002cond.mat..6393Z" } } }
