Effect of electron-phonon coupling in the ARPES spectra of the tri-layer cuprate BiSrCaCuO
S. Ideta, T. Yoshida, M. Hashimoto +9
Angle-resolved photoemission spectroscopy using tunable low energy photons allows us to study the quasi-particle (QP) dispersions of the inner and outer CuO2 planes (IP and OP) sep…
Two-fold symmetry flattens Dirac cone of surface state at W(110)
K. Miyamoto, A. Kimura, T. Okuda +6
The symmetry of the W(110) surface influences strongly the spin-polarized Dirac-cone-like surface state within a spin-orbit-induced symmetry gap. We present a detailed ang…
Observation of a Highly Spin Polarized Topological Surface State in GeBiTe
K. Okamoto, K. Kuroda, H. Miyahara +10
Spin polarization of a topological surface state for GeBiTe, the newly discovered three-dimensional topological insulator, has been studied by means of the state of the art…
Anomalous momentum dependence of the multiband electronic structure of FeSe_1-xTe_x superconductors induced by atomic disorder
Takaaki Sudayama, Yuki Wakisaka, Daiki Ootsuki +7
When periodicity of crystal is disturbed by atomic disorder, its electronic state becomes inhomogeneous and band dispersion is obscured. In case of Fe-based superconductors, disord…
Topological Surface States with Persistent High Spin Polarization across Dirac Point in BiTeSe and BiSeTe
K. Miyamoto, A. Kimura, T. Okuda +9
Helical spin textures with the marked spin polarizations of topological surface states have been firstly unveiled by the state-of-the-art spin- and angle-resolved photoemission spe…
Orbital Degeneracy and Peierls Instability in Triangular Lattice Superconductor IrPtTe
D. Ootsuki, Y. Wakisaka, S. Pyon +8
We have studied electronic structure of triangular lattice IrPtTe superconductor using photoemission spectroscopy and model calculations. Ir core-level photoem…
