]I (ET = bis(ethylenedithio)tetrathiafulvalene) has previously been reported as both a superconductor and an insulator. Examination of each single crystal revealed that the electrical properties are affected by slight differences in the conformation of one of the ethylene groups of ET, which is not involved in the conduction pathways.
We have found that the electrical properties of an organic charge transfer salt are qualitatively affected by slight differences in the conformation of one of the ethylene groups, which is not involved in the conduction pathways. |
