One Dimensional Organic Superconductivity in (TMTSF)₂PF₆ and (TMTSF)₂C10₄ Detected Via Tunnel Spectroscopy

Electron tunnelling data in (TMTSF)2X-GaSb Schottky barriers support the idea that strong superconducting fluctuations exist in quasi-one-dimensional (TMTSF) X up to temperatures which are about one order o$ magnitude higher than the 3-D ordering critical temperature. Other tunnelling data tend to in- dicate that stabilization of superconductivity is possible at high temperature via chain cross-linking.
