Hoesch, Aifeng Wang, Xianhui Chen, Jiangping Hu, Hong Ding, and Hai-Hu Wen Scanning tunneling spectroscopy and angle-resolved photoemission spectroscopy have been investigated on single-crystal samples of KFe 2 As 2 . A Van Hove singularity (VHS) has been directly observed just a few meV below the Fermi level ( E F ) of superconducting KFe 2 As 2 , which locates in the middle of the … [Phys. Rev.
