| 英文摘要 | As a follow-up of our previous work on pressure-induced metallization of the 2h(c)-mos2 [chi et al., phys. rev. lett. 113, 036802 (2014)], here we extend pressure beyond the megabar range to seek after superconductivity via electrical transport measurements. we found that superconductivity emerges in the 2h(a)-mos2 with an onset critical temperature t-c of ca. 3 k at ca. 90 gpa. upon further increasing the pressure, tc is rapidly enhanced beyond 10 k and stabilized at ca. 12 k over a wide pressure range up to 220 gpa. synchrotron x-ray diffraction measurements evidenced no further structural phase transition, decomposition, and amorphization up to 155 gpa, implying an intrinsic superconductivity in the 2h(a)-mos2. dft calculations suggest that the emergence of pressure-induced superconductivity is intimately linked to the emergence of a new flat fermi pocket in the electronic structure. our finding represents an alternative strategy for achieving superconductivity in 2h-mos2 in addition to chemical intercalation and electrostatic gating. |
