Observation of a robust zero-energy bound state in iron-based superconductor Fe(Te,Se)
Abstract
The symmetry of Cooper pairs in iron-based superconductors is an issue under continued investigation. A scanning tunnelling study of Fe(Te,Se) reveals a robust zero-energy bound state, providing evidence for a non-trivial pairing symmetry.
