详细的场和频率相关电导率测量报告见${（\mathrm{TMTSF}）}_{2}$P${\mathrm{F}}_{6}$。没有发现阈值场和一个小的介电常数，这意味着没有恢复力。没有发现非线性区域中存在宽带或窄带噪声的证据。这与高迁移率的初步观察一起表明，单粒子效应在很大程度上是造成过渡以下的非线性电导率的原因。
Detailed field- and frequency-dependent conductivity measurements are reported in ${(\mathrm{TMTSF})}_{2}$P${\mathrm{F}}_{6}$. No threshold field and a small dielectric constant are found, implying the absence of restoring forces. No evidence is found for wide- or narrow-band noise in the nonlinear regime. This, together with the preliminary observation of a high mobility, suggests that single-particle effects are largely responsible for the nonlinear conductivity below the transition.
