Zero-bias conductance peak in detached flakes of superconducting 2H-TaS${}_2$ probed by scanning tunneling spectroscopy

J. A. Galvis, L. Chirolli, I. Guillamon +5

We report an anomalous tunneling conductance with a zero bias peak in flakes of superconducting 2H-TaS${}_2$ detached through mechanical exfoliation. To explain the observed phenomen…
