On the origin of critical nematic fluctuations in pnictide superconductors
S. -F. Wu, W. -L. Zhang, L. Li +6
We employ polarization-resolved Raman spectroscopy to study critical nematic fluctuations in Ba(FeAu)As superconductors above and across well separated tetragon…
Stress-induced nematicity in EuFe2As2 studied by phononic Raman spectroscopy
W. -L. Zhang, Athena S. Sefat, H. Ding +2
We use polarized Raman scattering to study the structural phase transition in EuFe2As2, the parent compound of the 122-ferropnictide superconductors. The in-plane lattice anisotrop…
On the origin of the electronic anisotropy in iron pnicitde superconductors
W. -L. Zhang, P. Richard, H. Ding +5
We use polarization-resolved Raman spectroscopy to study the anisotropy of the electronic characteristics of the iron-pnictide parent compounds FeAs (~=~Eu, Sr).…
Electron-Hole Asymmetry in Superconductivity of Pnictides Originated from the Observed Rigid Chemical Potential Shift
M. Neupane, P. Richard, Y. -M. Xu +12
We have performed a systematic photoemission study of the chemical potential shift as a function of carrier doping in a pnictide system based on BaFeAs. The experimentally…
