Abstract
We report on the first measurements of thermal conductivity in the sup erconducting state of (TMTSF)(2)ClO4. The electronic contribution to h eat transport is found to decrease rapidly below T-c, indicating the a bsence 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.
