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 ( $[R/R_0 \,\lt\, 1]$ ).
