Description

The effect of electron-irradiation-induced defects on the non-Ohmic dc conductivity of tetrathiafulvalene tetracyanoquinodimethane (TTF-TCNQ) has been studied. The threshold field (E/sub T/) for non-Ohmic transport increases linearly with the defect concentration. This impurity study lends strong support to the explanation of the nonlinear conductivity in TTF-TCNQ by the depinning of the charge-density-wave condensate in strong electric fields. Both the nonlinear current and the Ohmic conductivity present a similar temperature dependence in the Peierls state
