摘要
Layered ZrTe3 crystallizes in an unusual structure that consists of both quasi-one-dimensional and quasi-two-dimensional features, conducive to the formation of charge-density wave and superconductivity, respectively. Bulk superconductivity up to 4 K in single crystalline samples of layered ZrTe3 has been successfully induced through high growth temperature. This procedure induces atomic disorders at both the Zr and the Te1 sites, as evident from the x-ray-diffraction study. As a result, the charge-density wave is partially suppressed without chemical doping or pressurization. The observation helps to understand the peculiar superconductivity of ZrTe3 and suggests a new path for the induction of superconductivity in complicated compounds with competitive orderings.
