Surface adatom conductance filtering in scanning tunneling spectroscopy of Co-doped BaFe2As2 iron pnictide superconductors
K. Koepernik, S. Johnston, E. van Heumen +5
We establish in a combination of ab initio theory and experiments that the tunneling process in scanning tunneling microscopy/spectroscopy on the A-122 iron pnictide superconductor…
Pseudogap-less high T superconductivity in BaCoFeAs
F. Massee, Y. K. Huang, J. Kaas +6
The pseudogap state is one of the peculiarities of the cuprate high temperature superconductors. Here we investigate its presence in BaCoFeAs, a member of the p…
Existence, character and origin of surface-related bands in the high temperature iron pnictide superconductor BaFe_{2-x}Co_{x}As_{2}
Erik van Heumen, Johannes Vuorinen, Klaus Koepernik +8
Low energy electron diffraction (LEED) experiments, LEED simulations and finite slab density functional calculations are combined to study the cleavage surface of Co doped BaFe_{2-…
Droplet-like Fermi surfaces in the anti-ferromagnetic phase of EuFeAs, an Fe-pnictide superconductor parent compound
S. de Jong, E. van Heumen, S. Thirupathaiah +15
Using angle resolved photoemission it is shown that the low lying electronic states of the iron pnictide parent compound EuFeAs are strongly modified in the magnetically or…
The cleavage surface of the BaFe_(2-x)Co_(x)As_(2) and Fe_(y)Se_(1-x)Te_(x) superconductors: from diversity to simplicity
F. Massee, S. de Jong, Y. Huang +4
We elucidate the termination surface of cleaved single crystals of the BaFe_(2-x)Co_(x)As_(2) and Fe_(y)Se_(1-x)Te_(x) families of the high temperature iron based superconductors.…
Nanoscale superconducting gap variations, strong coupling signatures and lack of phase separation in optimally doped BaFe1.86Co0.14As2
F. Massee, Y. Huang, R. Huisman +3
We present tunneling data from optimally-doped, superconducting BaFe1.86Co0.14As2 and its parent compound, BaFe2As2. In the superconductor, clear coherence-like peaks are seen acro…
A high resolution, hard X-ray photoemission investigation of BaFeAs: moderate influence of the surface and evidence for a low degree of Fe 3d - As 4p hybridization of the near-E electronic states
S. de Jong, Y. Huang, R. Huisman +6
Photoemission data taken with hard X-ray radiation on cleaved single crystals of the barium parent compound of the MFeAs pnictide high temperature superconductor family are…
