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…
Microscopic analysis of the chemical reaction between Fe(Te,Se) thin films and underlying CaF
A. Ichinose, I. Tsukada, M. Hanawa +5
To understand the chemical reaction at the interface of materials, we performed a transmission electron microscopy (TEM) observation in four types of Fe(Te,Se) superconducting thin…
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…
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…
Deviation from the Wiedemann-Franz law induced by nonmagnetic impurities in overdoped La_{2-x}Sr_{x}CuO_{4}
X. F. Sun, B. Lin, X. Zhao +4
To investigate the validity of the Wiedemann-Franz (WF) law in disordered but metallic cuprates, the low-temperature charge and heat transport properties are carefully studied for…
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…
