我们回顾了一系列扩展的低维有机Bechgaard导体，这是托管的第一个有机超导体（TMTSF）2PF6的输运和光学性质。结果表明，这个家庭的所有化合物是一维莫特绝缘体的激活能纵向运输取决于它们的化学组成和压力下减少。在运输结果中的活化能消失在（化学）压力引起的维度交叉，而间隙功能仍然是可观察到的远红外光谱。特别地，根据横向传输的数据，即使当纵向传输变成金属状时，也可以观察到准粒子谱中的间隙的签名。在这篇综述中，我们讨论了与低维相互作用电子气物理学相关的各种相关问题和概念，如非费米液体行为，维度交叉，特别是Luttinger液体状态的出现。
We review the transport and optical properties of an extended series of low dimensional organic Bechgaard conductors, which are hosting the first organic superconductor (TMTSF)2PF6. It is shown that all compounds of this family are one-dimensional Mott insulators with an activation energy for longitudinal transport depending on their chemical composition and decreasing under pressure. This activation energy in the transport results vanishes at a (chemical) pressure induced dimensionality crossover, while a gap feature is still observable in the far-infrared spectrum. Particularly, according to the data of transverse transport, the signature of a gap in the quasi particle spectrum is observable even when the longitudinal transport becomes metal-like. In this survey, we address a variety of relevant problems and concepts associated with the physics of an interacting electron gas in low dimensions, such as nonFermi liquid behavior, dimensionality crossover, and specifically the appearance of the Luttinger liquid state.
