Probing bulk superconductivity in centrosymmetric Te-doped PtBi$_2$ single crystals
The Weyl semimetal $\gamma$-PtBi$_2$ has been shown to be one of the most promising novel materials, recently proposed as a topological i-wave superconductor. A crucial requirement for observing this physics is the absence of inversion symmetry in its trigonal $P31m$ crystal structure. Centrosymmetry has been reported...
