英文摘要It was found that selenium doping can suppress the charge-density-wave (CDW) order and induce bulk superconductivity in ZrTe3. The observed superconducting dome suggests the existence of a CDW quantum critical point (QCP) in ZrTe3-xSex near x approximate to 0.04. To elucidate the superconducting state near the CDW QCP, we measure the thermal conductivity of two ZrTe3-xSex single crystals (x = 0.044 and 0.051) down to 80 mK. For both samples, the residual linear term kappa(0)/T at zero field is negligible, which is a clear evidence for nodeless superconducting gap. Furthermore, the field dependence of kappa(0)/T manifests a multigap behavior. These results demonstrate multiple nodeless superconducting gaps in ZrTe3-xSex, which indicates conventional superconductivity despite of the existence of a CDW QCP.
