论文摘要
最近，拓扑超导体成为实现Majorana费米子的平台，该平台在拓扑量子计算中具有潜在的应用。这些材料中的超导性可以通过化学掺杂，高压或接近效应来实现。本文中，我们报告了重掺杂的II型Weyl semimetal Nite2的单晶中的新兴超导性。磁性和传输测量值强调了在NI位点取代的磁性和运输测量值在2.36 K的最高温度下诱导超导性。HALL效应和特定的热量测量表明，RE取代是掺杂孔，并通过声子软化和增强电子量子耦合来促进超导性的出现。
Recently topological superconductors emerge as a platform to realise Majorana Fermions which has potential application in topological quantum computation. Superconductivity in these materials can be realised by chemical doping, high pressure or proximity effect. Herein we report the emergent superconductivity in single-crystals of Re doped type-II Weyl semimetal NiTe2. The magnetic and transport measurements highlight that Re substitution in Ni-site induces superconductivity at a maximum temperature of 2.36 K. Hall effect and specific heat measurements indicate that Re substitution is doping hole and facilitates the emergence of superconductivity by phonon softening and enhancing the electron-phonon coupling.
