Author(s): Shun Chi, S. Grothe, Ruixing Liang, P. Dosanjh, W. N. Hardy, S. A. Burke, D. A. Bonn, and Y. Pennec 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 in this system. Spectra at 2 K show two nodeless superconducting gaps with Δ 1 =5.3±0.1 meV and Δ 2 =2.5±0.2 meV. The gaps c... [Phys. Rev. Lett. 109, 087002] Published Tue Aug 21, 2012
