ONE-DIMENSIONAL ORGANIC SUPERCONDUCTIVITY - AN INVESTIGATION THROUGH ELECTRON SCHOTTKY TUNNELLING IN N-GASB-(TMTSF)2PF6 JUNCTIONS UNDER PRESSURE

Observation of a large pseudo-gap at the Fermi level by Schottky tunneling of electrons from N doped-GaSb into the organic superconductor (TMTSF)//2 PF//6 under a pressure of 11 kbar (T//c equals 1 K) establishes, on an unambiguous experimental basis the one-dimensional character of the low temperature superconducting divergence and so justifies the presence of 1-D superconducting fluctuations to high temperatures. The intrachain pairing energy 2 DELTA (O) equals 3. 6 Mev derived from tunneling characteristics emphasizes the strength of the superconducting channel in the family of organic superconductors (TMTSF)//2X.
