Quasi-one-dimensional superconductivity in the pressurized charge-density-wave conductor HfTe3

Abstract HfTe3 single crystal undergoes a charge-density-wave (CDW) transition at T CDW = 93 K without the appearance of superconductivity (SC) down to 50 mK at ambient pressure. Here, we determined its CDW vector q = 0.91(1) a* + 0.27(1) c* via low-temperature transmission electron microscope and t...
