Point-contact Andreev-reflection spectroscopy in Fe(Te,Se) films: multiband superconductivity and electron-boson coupling
D. Daghero, P. Pecchio, G. A. Ummarino +6
We report on a study of the superconducting order parameter in Fe(TeSe) thin films (with different Se contents: x=0.3, 0.4, 0.5) by means of point-contact Andreev-ref…
Hall effect of FeTe and Fe(Se_1-x_Te_x_) thin films
I. Tsukada, M. Hanawa, Seiki komiya +4
The Hall effect is investigated in thin-film samples of iron-chalcogenide superconductors in detail. The Hall coefficient (RH) of FeTe and Fe(Se1-xTex) exhibits a similar positive…
Mobility analysis of FeTe thin films
I. Tsukada, M. Hanawa, Seiki Komiya +4
The Hall effect is investigated in detail for nonsuperconducting and superconducting FeTe thin films. The Hall coefficient commonly exhibits a sign reversal from positive in a high…
Terahertz conductivity spectroscopy of Co-doped BaFeAs Thin Film
D. Nakamura, Y. Imai, A. Maeda +3
We investigated the complex conductivity spectrum of a Co-doped BaFeAs epitaxial thin film in the THz region. In the normal state, the complex conductivity shows a Drude-ty…
Hall effect in superconducting Fe(Se0.5Te0.5) thin films
I. Tsukada, M. Hanawa, S. Komiya +4
The Hall effect is investigated for eight superconducting Fe(Se_0.5_Te_0.5_) thin films grown on MgO and LaSrAlO_4_ substrates with different transition temperatures (T_c_). The no…
Angle-Resolved Photoemission Spectroscopy of Iron-Chalcogenide Superconductor Fe1.03Te0.7Se0.3 : Strong-Coupling Superconductivity and Universality of Inter-Band Scattering
K. Nakayama, T. Sato, P. Richard +8
We have performed high-resolution angle-resolved photoemission spectroscopy of iron-chalcogenide superconductor Fe1.03Te0.7Se0.3 (Tc = 13 K) to investigate the electronic structure…
