Electrodynamics of Bechgaard Salts: Optical Properties of One-Dimensional Metals
Figure 19
Temperature dependence of the mode parameters obtained from fitting the optical properties of obtained from powder transmission measurements. (a) Zero-frequency conductivity and (b) scattering rate of the Drude contribution to the optical conductivity of . (c) Parameters of the mode that develop around 7 : denotes the eigenfrequency, the width, and the mode strength (spectral weight). Temperature dependence of the parameters of the 30 mode: (d) the spectral weight given as a mode strength , (e) the center frequency , and (f) the damping of the mode. The lines connect the data points. The open symbols correspond to a second mode that has to be introduced at slightly higher frequencies for a complete description.
