Dominant $s$-wave superconducting gap in PdTe${}_2$ observed by tunneling spectroscopy on side-junctions

J. A. Voerman, J. C. de Boer, T. Hashimoto +3

We have fabricated superconductor-normal metal side-junctions with different barrier transparencies out of PdTe${}_2$ crystalline flakes and measured the differential conductance spe…
