Abstract
One of the most fundamental phenomena of the charge density wave (CDW) dynamics is, the nonlinear conduction of the collective electron transport due to the sliding condensate [1]. At temperatures not very far below the phase transition the CDW is depinned from the underlying lattice above a relatively low threshold field of about 10 to 100 mV/cm. In this temperature range the thermally excited quasiparticles are still of importance and the collective current, jCDW, is superimposed on the normal current, jn. In contrast, in the T→ 0 limit the linear term due to single particle current is absent and the CDW dynamics is also different: a novel type of collective conduction emerges, where the steep current rise is solely due to the moving condensate [2]. The most significant features of the two types of nonlinear conduction are well illustrated by the I-V characteristics of K0.3MoO3 shown in Fig. 1.
