Non-ohmic electrical transport in the charge-density wave state of (2,5(OCH3)2DCNQI)2Li

Electric-field-dependent conductivity measurements are reported in the low-temperature charge density wave state of the organic conductor (2.5(OCH3)2DCNQI)2Li. We associate non-linear conductivity to the sliding of 2kI. CDW pinned by commensurability to the background lattice. The sliding mechanism ceases to be valid below 25K concomitantly with the onset of the variable range hopping in single particle conduction.
