Field-induced dielectric response saturation in $$o$$ -TaS3
Abstract
The temperature and electric field dependent conductivity spectra of o-TaS3 sample with 10 μm2 in cross section were measured. Besides the classical electric threshold ET₋Cl, we observed another novel threshold ET₋N at a larger electric field, where an S-shaped I-V relation revealed. The appearance of ET₋N may be due to the establishment of coherence among small charge-density- wave domains. Under a stable field E > ET-N, a sharp dispersion emerged below kHz. At a fixed temperature, the scattering rate of the charged condensate was extremely small and decreased with increasing field. With decreasing temperature, the scattering Fröhlic-mode conductivity would be consistent with the meta-stable state.
