Abstract

τ-phase organic quasi-two-dimensional conductors have a 4-fold single Fermi surface (FS) from band calculation. At low temperature, the resistivity turns into semiconducting, whereas Shubnikov-de Haas oscillations (SdH) have been observed. The SdH signal includes two frequencies that are inconsistent with the band calculation. Recently, we found the superstructure of this salt below 245 K by X-ray study. This result may explain the contradiction between observation and calculation for the FS.
