Nodeless superconducting gap in the candidate topological superconductor Sn${}_{1-x}$In${}_x$Te for x = 0.7

M. P. Smylie, Kaya Kobayashi, T. Takahashi +4

High-pressure synthesis techniques have allowed for the growth of Sn${}_{1-x}$In${}_x$Te samples beyond the ambient In-saturation limit of $x$ = 0.5 (T${}_c\sim$ 4.5 K). In this study,…
