Electrodynamics of Bechgaard Salts: Optical Properties of One-Dimensional Metals
Figure 4
Temperature dependence of the dc resistivity of several Fabre and Bechgaard salts. As the temperature is reduced, the charges become increasingly localized in and , before the charge-ordered state is entered below 100 K. shows a transition from a metal-like state directly into the charge-ordered state at K. undergoes a SDW transition at K. Only remains metallic all the way down to approximately K where it becomes superconducting (after Dressel et al. [36–39]).
