Electrodynamics of Bechgaard Salts: Optical Properties of One-Dimensional Metals
Figure 14
(a) The low-frequency optical reflectivity of measured perpendicular to the chains (). The spin-density-wave gap opens as the temperature is lowered below 15 K. The solid lines are optical reflectivity data, the symbols indicate the results of the THz measurements; the dashed line represents the extrapolation for the Kramers-Kronig analysis. (b) The corresponding optical conductivity of perpendicular to the chain direction as obtained by the Kramers-Kronig transformation of the reflectivity data (after [43, 77]).
