Figure 2
Non-linear electrical conductivity of NbSe3 in the CDW state. The normalized residual resistance R/R0 = (1/R0) dV/dI (V = voltage, I = current, R0 is value of R at V = 0) is plotted as a function of the electrical field (E). Ohm's law is expressed by R/R0 = 1 for low fields. Above a certain threshold field (E0), incommensurate CDW crystals have a second conduction path due to sliding of the CDW that results in a resistance smaller than that given by Ohm's law ([R/R_0 \,\lt\, 1]).
