Abstract

We report on the first measurements of thermal conductivity in the superconducting state of (TMTSF)₂ClO₄. The electronic contribution to heat transport is found to decrease rapidly below T_c, indicating the absence of low-energy electronic excitations. We argue that this result provides strong evidence for a nodeless superconducting gap function but does not exclude a possible unconventional order parameter.
