Surface Circular Photogalvanic Effect in Tl-Pb Monolayer Alloys on Si(111) with Giant Rashba Splitting
Ibuki Taniuchi, Ryota Akiyama, Rei Hobara +1
We have found that surface superstructures made of "monolayer alloys" of Tl and Pb on Si(111), having giant Rashba effect, produce non-reciprocal spin-polarized photocurrent via ci…
Two-dimensional superconductivity of the Ca-intercalated graphene on SiC: vital role of the interface between monolayer graphene and the substrate
Haruko Toyama, Ryota Akiyama, Satoru Ichinokura +10
Ca-intercalation has opened a way for superconductivity in graphene on SiC. However, the atomic and electronic structures being critical for superconductivity are still under discu…
Controlling of the Dirac band states of Pb-deposited graphene by using work function difference
Y. Tsujikawa, M. Sakamoto, Y. Yokoi +5
We have performed scanning tunneling microscope (STM) and angle-resolved photoemission spectroscopy (ARPES) in Pb-deposited bilayer Graphene (BLG) on SiC(0001) substrate to investi…
Superconducting proximity effect in a Rashba-type surface state of Pb/Ge(111)
H. Huang, H. Toyama, L. V. Bondarenko +8
The Rashba superconductor, in which spin-splitting bands become superconducting, is fascinating as a novel superconducting system in low dimensional systems. Here, we present the r…
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…
Inverse Spin Hall Effect Induced by Asymmetric Illumination of Light on Topological Insulator BiSe
Di Fan, Rei Hobara, Ryota Akiyama +1
Using circularly polarized light is an alternative to electronic ways for spin injection into materials. Spins are injected at a point of the light illumination, and then diffuse a…
