Abstract
The $b$-axis conductivity was measured as a function of the electric field $E$ for temperatures $T>34$ K in the one-dimensional organic conductor TTF-TCNQ (tetrathiafulvalene-tetracyano-quinodimethane). Deviations from Ohm's law, with a threshold field ${E}_{T}$, have been observed for $T<60$ K. ${E}_{T}$ reaches a minimum of 0.25 V/cm just below the onset of the 54-K Peierls transition before increasing to 6.4 V/cm at 34 K. The results are discussed in terms of the depinning of the charge-density-wave condensate at high fields; the interaction between the two types of chains in TTF-TCNQ is included.
