Weak-link Josephson Junctions Made from Topological Crystalline Insulators

R. A. Snyder, C. J. Trimble, C. C. Rong +3

We report on the fabrication of Josephson junctions using the topological crystalline insulator Pb${}_{0.5}$Sn${}_{0.5}$Te as the weak link. The properties of these junctions are chara…
