2 Jun 2006 | Journal: | Phys Rev Lett, 96 (21), 216402 | Abstract: | Non-Fermi liquid behavior is shown to occur in two-dimensional metals which are close to a charge ordering transition driven by the Coulomb repulsion. A linear temperature dependence of the scattering rate together with an increase of the electron effective mass occur above T*, a temperature scale much smaller than the Fermi temperature. It is shown that the anomalous temperature dependence of the optical conductivity of the quasi-two-dimensional organic metal alpha-(BEDT-TTF)2MHg(SCN)4, with M = NH4 and Rb, above T* = 50-100K, agrees qualitatively with predictions for the electronic properties of nearly charge ordered two-dimensional metals. | Source: | PubMed, pmid16803258 | Other source: | [GID 697335] cond-mat/0601482 | Services: | Forum | Review | Favorites |
