Pressure-induced double-dome superconductivity in doped kagome metal Cs(V0.86Ta0.14)3Sb5 without charge density wave
Researchers measured resistance under high pressure on Ta-doped Cs(V0.86Ta0.14)3Sb5 to test for double-dome superconductivity without a charge density wave (CDW). The results revealed two superconducting domes in the T-P phase diagram, confirming that this feature is an intrinsic and universal property of the AV3Sb5 family even when long-range CDW order is absent.
