Enhancement of the superconducting transition temperature due to multiband effect in the topological nodal-line semimetal Pb${}_{1-x}$Sn${}_x$TaSe${}_2$

K. Kumarasinghe, A. Rahman, M. Tomlinson +4

We report a systematic study of the normal-state and superconducting properties of single crystal Pb${}_{1-x}$Sn${}_x$TaSe${}_2$ $(0\le x\le 0.23)$. Sn doping enhances the superco…
