Ultrafast unbalanced electron distributions in quasicrystalline 30° twisted bilayer graphene
T. Suzuki, T. Iimori, S. J. Ahn +15
Layers of twisted bilayer graphene exhibit varieties of exotic quantum phenomena1-5. Today, the twist angle Θ has become an important degree of freedom for exploring novel states o…
Two-dimensional conducting layer on SrTiO surface induced by hydrogenation
Y. Takeuchi, R. Hobara, R. Akiyama +5
We found that a surface state induced by hydrogenation on the surface of SrTiO(001) (STO) did not obey the rigid band model, which was confirmed by in situ electrical resisti…
Photoemission Circular Dichroism and Spin Polarization of the Topological Surface States in Ultrathin Bi2Te3 Films
C. -Z. Xu, Y. Liu, R. Yukawa +4
Circular dichroism (CD) observed by photoemission, being sensitive to the orbital and spin angular momenta of the electronic states, is a powerful probe of the nontrivial surface s…
Interface electronic structure at the topological insulator - ferrimagnetic insulator junction
Y. Kubota, K. Murata, J. Miyawaki +15
An interface electron state at the junction between a three-dimensional topological insulator (TI) film of Bi2Se3 and a ferrimagnetic insulator film of Y3Fe5O12 (YIG) was investiga…
Deviation from Fermi-liquid behavior in two-dimensional surface states of Au-induced nanowires on Ge(001) by correlation and localization
K. Yaji, R. Yukawa, S. Kim +7
The electronic states of Au-induced atomic nanowires on Ge(001) (Au/Ge(001) NWs) have been investigated by angle-resolved photoelectron spectroscopy with linearly polarized light.…
Direct evidence of spin-split one-dimensional metallic surface state on Si(557)-Au
Taichi Okuda, Koji Miyamoto, Yasuo Takeichi +8
We report unprecedented evidence of a spin split one-dimensional metallic surface state for the system of Si(557)-Au obtained by means of high-resolution spin- and angle-resolved p…
