    Abstract

    We have performed a thermoelectric-power study of the organic conductor (TMTSF)2PF6 which exhibits a type of bulk quantum Hall effect (QHE), resulting from a cascade of magnetic-field-induced spin-density-wave (FISDW) transitions. The FISDW are characterized by a sharp increase in thermopower as the temperature is lowered through the transition temperature, followed by an exponential decrease as temperature approaches zero. This suggest a temperature-dependent gap leading to collective QHE-like transport. Most surprising is the vanishing thermopower in the insulating n=0 state.
