Andreev reflection without Fermi surface alignment in high-Tc van der Waals heterostructures

We address the controversy over the proximity effect between topological materials and high- T _c superconductors. Junctions are produced between Bi _2 Sr _2 CaCu _2 O ${}_{8+\delta }$ and materials with different Fermi surfaces (Bi _2 Te _3  and graphite). Both cases reveal tunneling spectra that a...
