Title: Superconductivity in irradiated charge-density-wave compounds 2H-NbSe/sub 2/, 2H-TaS/sub 2/, and 2H-TaSe/sub 2/

Abstract

Superconducting T/sub c/ can be increased by a low concentration, less than 1%, of irradiation-induced defects in the layered charge-density-wave (CDW) compounds 2H-NbSe/sub 2/, 2H-TaS/sub 2/, and 2H-TaSe/sub 2/. This is due to the pinning effect of the defects which perturbs the long-range coherence of the CDW. Resistive transitions show tails below a first drop, suggesting inhomogeneous superconductivity. Such effects are proposed to be related to CDW domains.
