英文摘要Topological nodal-line semimetal SrAs(3)hosts a simple nodal loop on the verge of Fermi level without distracting trivial states, providing a good platform for further investigations of electronic quantum states. Here, a report on pressure-driven superconductivity in SrAs(3)single crystal is provided and the interplay between the crystal structure, electronic state, and superconductivity is clarified therein. The comprehensive high-pressure experiments, i.e., synchrotron X-ray diffraction, electrical transport, and Raman spectroscopy, consistently reveal a critical pressureP(c) approximate to 25 GPa. AroundP(c), a superconducting transition appears, concomitant with the formation of high-pressure cubicPm-3mphase. Meanwhile, the superconducting transition temperatureT(c)and hole carrier density increase synchronously aboveP(c). This finding demonstrates that the emerging superconductivity in SrAs(3)stems from the high-pressure cubic phase on the one hand, and shows that the evolution ofT(c)(P) is intimately correlated with the enhanced density of states near the Fermi level on the other hand.
