Hidden -Linear Scattering Rate in BaKFeAs Revealed by Optical Spectroscopy
Y. M. Dai, B. Xu, B. Shen +5
The optical properties of BaKFeAs have been determined in the normal state for a number of temperatures over a wide frequency range. Two Drude terms, re…
Two pseudogaps with different energy scales at the antinode of the high-temperature BiSrCuO superconductor using angle-resolved photoemission spectroscopy
K. Nakayama, T. Sato, Y. -M. Xu +8
We have performed high-resolution angle-resolved photoemission spectroscopy on single-layered cuprate BiSrCuO to clarify the origin of the pseudogap. By using various p…
Optical conductivity of Ba0.6 K0.4 Fe2 As2 : The effect of in-plane and out-of-plane doping in the superconducting gap
Y. M. Dai, B. Xu, B. Shen +3
We measured the in-plane optical conductivity of a nearly optimally doped (Ba,K)Fe2As2 single crystal with Tc = 39.1 K. Upon entering the superconducting state the optical conducti…
Anisotropic Structure of the Order Parameter in FeSe0.45Te0.55 Revealed by Angle Resolved Specific Heat
B. Zeng, G. Mu, H. Q. Luo +7
The symmetry and structure of the superconducting gap in the Fe-based superconductors are the central issue for understanding these novel materials. So far the experimental data an…
