Negative differential resistance (NDR) was observed in the most well known organic conductor, TTF-TCNQ, in its low-temperature Peierls insulator phase below 53 K. The voltage-current (V−I) characteristics below this temperature, measured by a four-probe method, exhibited unique NDR behavior, in which the dV/dI versus conductivity (σ) plots had the inflection points at the three σ values without depending on temperature. These σ values were found to coincide with the conductivities at the three transition temperatures (53, 49, and 38 K) for the formation of the charge-density waves in TTF-TCNQ. This suggests that the electronic structure of the Peierls insulating phase of TTF-TCNQ is governed by the total carrier density, which is determined by not only thermal excitation but also carrier injection.
