Andreev Reflection Spectroscopy of Topological Superconductor Candidate Nb${}_x$Bi${}_2$Se${}_3$

Cihan Kurter, Aaron Finck, Erik Huemiller +10

We study unconventional superconductivity in thin exfoliated single crystals of a promising 3D topological superconductor candidate, Nb-doped Bi${}_2$Se${}_3$ through Andreev reflectio…
