Evidence of incoherent carriers associated with resonant impurity levels and their influence on superconductivity in the anomalous superconductor PbTlTe
P. Giraldo-Gallo, P. Walmsley, B. Sangiorgio +9
We present a combined experimental and theoretical study of the evolution of the Fermi surface of the anomalous superconductor PbTlTe as a function of thallium concentr…
Structural and magnetic phase transitions in CaLaFeAs with electron overdoped FeAs layers
Shan Jiang, Chang Liu, Huibo Cao +15
We report a study of the CaLaFeAs single crystals. We unravel a monoclinic to triclinic phase transition at 58 K, and a paramagnetic to stripe antiferromagnet…
What controls the phase diagram and superconductivity in Ru substituted BaFeAs?
R. S. Dhaka, Chang Liu, R. M. Fernandes +8
We use high resolution angle-resolved photoemission to study the electronic structure of the iron based high-temperature superconductors Ba(FeRu)As as a functio…
Importance of Fermi surface topology for high temperature superconductivity in electron-doped iron arsenic superconductors
Chang Liu, A. D. Palczewski, Takeshi Kondo +8
We used angle resolved photoemission spectroscopy and thermoelectric power to study the poorly explored, highly overdoped side of the phase diagram of Ba(Fe1-xCox)2As2 high tempera…
Surface-driven electronic structure in LaFeAsO studied by angle resolved photoemission spectroscopy
Chang Liu, Yongbin Lee, A. D. Palczewski +6
We measured the electronic structure of an iron arsenic parent compound LaFeAsO using angle resolved photoemission spectroscopy (ARPES). By comparing with a full-potential Linear A…
Critical change in the Fermi surface of iron arsenic superconductors at the onset of superconductivity
Chang Liu, Takeshi Kondo, Rafael M. Fernandes +10
The phase diagram of a correlated material is the result of a complex interplay between several degrees of freedom, providing a map of the material's behavior. One can understand (…
Unusual Fermi surface nesting in parent compounds of iron arsenic high temperature superconductors revealed by Angle Resolved Photoemission Spectroscopy
Takeshi Kondo, R. M. Fernandes, R. Khasanov +10
We use angle resolved photoemission spectroscopy (ARPES) to study the band structure of BaFe2As2 and CaFe2As2, two of the parent compounds of the iron arsenic high temperature supe…
Three- to Two-Dimensional Transition of the Electronic Structure in CaFe2As2 - parent compound for an iron arsenic high temperature superconductor
Chang Liu, Takeshi Kondo, Ni Ni +9
We use angle-resolved photoemission spectroscopy (ARPES) to study the electronic properties of CaFe2As2 - parent compound of a pnictide superconductor. We find that the structural…
Momentum dependence of the superconducting gap in NdFeAsO1-xFx single crystals measured by angle resolved photoemission spectroscopy
Takeshi Kondo, A. F. Santander-Syro, O. Copie +8
We use angle resolved photoemission spectroscopy (ARPES) to study the momentum dependence of the superconducting gap in NdFeAsO1-xFx single crystals. We find that the Gamma hole po…
