| 英文摘要 | Studies on the preparation and physical properties of phase-pure 1T′-MoS2are still scarce although a 1T′ phase MX2(M = Mo and W; X = Se and Te) has recently been reported to be a Weyl semimetal, a quantum spin Hall insulator, and a superconductor. Herein, we report a perfect single-layer 1T′-MoS2structure based on edge-sharing octahedra. Pure 1T′-MoS2nanosheets were successfully prepared using LiMoS2single crystals. The arrangement of zig-zag Mo-Mo chains in the 1T′-MoS2layer evolved from that of parent Mo-Mo diamond-like chains in LiMoS2crystals after the removal of all lithium ions. A well-defined 1T′-type lattice structure was observed and characterized by scanning transmission electron microscopy, X-ray photoelectron spectroscopy, and Raman spectroscopy. Surprisingly, superconductivity with an onset transition temperature (Tc) of 4.6 K has been observed in the lithium-free 1T′-MoS2nanosheets, which is not observed in semiconducting bulk or single-layer 2H-MoS2. © 2017 The Royal Society of Chemistry. |
