摘要
Current-voltage characteristics are measured on the title organic conductor. The current dependence of the resistance shows non-ohmic behaviour in the low temperature density wave phase. This is the first observation of the non-linear behaviour in the low temperature phase. The magnitude of the non-ohmicity is a few percent of the ohmic resistance for the low current density. The threshold voltage is found to be an order of mV/cm, and it decreases with decreasing temperature.
