Description:
Author(s): Lei Shan, Jing Gong, Yong-Lei Wang, Bing Shen, Xingyuan Hou, Cong Ren, Chunhong Li, Huan Yang, Hai-Hu Wen, Shiliang Li, and Pengcheng Dai We used high-resolution scanning tunneling spectroscopy to study the hole-doped iron pnictide superconductor Ba 0.6 K 0.4 Fe 2 As 2 ( T c =38 K ). Features of a bosonic excitation (mode) are observed in the measured quasiparticle density of states. The bosonic features are intimately associated with the super... [Phys. Rev.
