Abstract
We have investigated the threshold properties of Rubidium blue bronze Rb0.3MoO3 under high dc electric field in a large temperature range 20-150Â K. The second threshold fields have been observed at temperature up to 102.4Â K, and have quasi-linear relationships with temperatures 20-45Â K and 55-100Â K, respectively. A novel crossover platform has been found firstly in the temperature dependence of the second threshold field ET2 at about 45-55Â K. The results indicate that the dynamical behavior of the second threshold effects may originate from different mechanisms. We suggest that the highly conducting state at 20-45Â K and 55-100Â K result from the undamped sliding motion of rigid CDW and current inhomogeneity, respectively.
