(Color online) characteristic of in a two-probe transport setup at . The red line is the fit to the predicted thermal creeps when the CDW is pinned, and the green line shows the for . The left inset shows the dimension of the sample and the experimental setup. The right inset for shows a transition point at .
(Color online) (a) Evolution of the half-width of the Bragg peak vs the applied voltage. According to the changes of the half-width, one can classify CDW into three phases: (I) the creeping CDW state, (II) the moving solid, and (III) the moving liquid. (b) The triplet phase change at different voltages. Note that in the sliding phase, is a direct evidence that the pinning forces become irrelevant. (c) Peak profiles at different voltages. The fits were obtained by convolution to the resolution function as measured on a nearby Bragg peak . The bar shows the resolution, 0.0033 [reciprocal lattice unit (r.l.u.)], along the longitudinal direction .
(Color online) Triplet phase change extrapolated from curve fitting of the three-wave diffraction profiles. The analysis is based on the dynamic theory for multiple diffraction, giving and 18° at and , respectively.
