Signature of Fermi arc surface states in Andreev reflection at the WTe${}_2$ Weyl semimetal surface

A. Kononov, O. O. Shvetsov, S. V. Egorov +3

We experimentally investigate charge transport through the interface between a niobium superconductor and a three-dimensional WTe${}_2$ Weyl semimetal. In addition to classical Andre…
