Observation of a Robust Zero-energy Bound State in Iron-based Superconductor Fe(Te,Se)

J. -X. Yin, Zheng Wu, J. -H. Wang +14

A robust zero-energy bound state (ZBS) in a superconductor, such as a Majorana or Andreev bound state, is often a consequence of non-trivial topological or symmetry related propert…
