热导率的第一个研究，$\kappa$，在准二维有机超导体的$\kappa$-（BEDT-TTF）$_2$X家庭揭示了类似的功能已经观察到的铜酸盐。超导性的发生与$\kappa$的突然增加有关，这可以通过施加适度的磁场来抑制。在低温下，一个有限的线性项-由于残余电子的贡献-得到解决。这一项的大小接近于非常规超导体中输运理论的预测。
The first study of thermal conductivity, $\kappa$, in a quasi-two-dimensional organic superconductor of the $\kappa$-(BEDT-TTF)$_2$X family reveals features analogous to those already observed in the cuprates. The onset of superconductivity is associated with a sudden increase in $\kappa$ which can be suppressed by the application of a moderate magnetic field. At low temperatures, a finite linear term - due to a residual electronic contribution- was resolved. The magnitude of this term is close to what is predicted by the theory of transport in unconventional superconductors.
