Sažetak
We have measured the temperature dependence of the electro-transmittance of the quasi-one dimensional charge-density-wave (CDW) conductor blue bronze at temperatures between 55 K and 125 K when square-wave voltages are applied to the sample. For voltages well-above the threshold for nonlinear current, the characteristic electro-optic relaxation time, at a given position in the sample, depends primarily on the CDW current, whereas the magnitude of the relative change in transmittance decreases with decreasing temperature even for constant CDW current. At lower voltages, the frequency dependence of the response broadens, suggesting non-uniform and temperature dependent barriers to CDW repolarization.
