Impact of Iron-site defects on Superconductivity in LiFeAs
Shun Chi, Ramakrishna Aluru, Udai Raj Singh +10
In conventional s-wave superconductors, only magnetic impurities exhibit impurity bound states, whereas for an s+- order parameter they can occur for both magnetic and non-magnetic…

Scanning tunneling spectroscopy of superconducting LiFeAs single crystals: Evidence for two nodeless energy gaps and coupling to a bosonic mode
Shun Chi, S. Grothe, Ruixing Liang +5
The superconducting compound, LiFeAs, is studied by scanning tunneling microscopy and spectroscopy. A gap map of the unreconstructed surface indicates a high degree of homogeneity…
