Electrodynamics of Bechgaard Salts: Optical Properties of One-Dimensional Metals
Figure 11
Measured (a) absorptivity and (b) conductivity of at 300 K, 100 K, and 20 K, for . The open symbols were obtained by the cavity perturbation technique. The solid symbols are from THz reflectivity measurements. The solid lines are infrared through ultraviolet reflectivity data. The dashed lines show the spectra which were used as the input for the KK calculations. The inset in (b) shows the total integrated spectral weight and the fraction in the zero-energy mode, both as functions of temperature, demonstrating that the spectral weight is not redistributed, and that only about 1% is in the Drude-like mode (after [44, 47]).
