Spatial Control of Charge Doping in n-Type Topological Insulators

Kazuyuki Sakamoto, Hirotaka Ishikawa, Takashi Wake +17

Spatially controlling the Fermi level of topological insulators and keeping its electronic states stable are indispensable processes to put this material into practical use for sem…

Non-charge-transfer origin of Tc Enhancement in a Surface Superconductor Si(111)-(root7xroot3)-In with Adsorbed Organic Molecules

Kenta Yokota, Shunsuke Inagaki, Wenxuan Qian +5

The effects of adsorption of Zn-phthalocyanine (ZnPc) molecules on the superconductivity of the Si(111)-(root7xroot3)-In surface are studied through transport measurements under ul…

Atomic-layer Rashba-type superconductor protected by dynamic spin-momentum locking

Shunsuke Yoshizawa, Takahiro Kobayashi, Yoshitaka Nakata +6

Spin-momentum locking is essential to the spin-split Fermi surfaces of inversion-symmetry broken materials, which are caused by either Rashba-type or Zeeman-type spin-orbit couplin…

Surface band characters of Weyl semimetal candidate material MoTe revealed by one-step ARPES theory

Ryota Ono, Alberto Marmodoro, Jakub Schusser +7

The layered 2D-material MoTe in the T crystal phase is a semimetal which has theoretically been predicted to possess topologically non-trivial bands corresponding to Weyl f…

Transforming a Surface State of Topological Insulator by a Bi Capping Layer

Han Woong Yeom, Sung Hwan Kim, Woo Jong Shin +7

We introduce a dinstint approach to engineer a topologically protected surface state of a topological insulator. By covering the surface of a topological insulator, Bi2Te2Se, with…

Spin-polarized angle-resolved photoelectron spectroscopy of the so-predicted Kondo topological insulator SmB6

Shigemasa Suga, Kazuyuki Sakamoto, Taichi Okuda +13

Undoped and slightly Eu-doped SmB6 show the opening of a gap with decreasing temperature below ~150 K. The spectral shapes near the Fermi level (EF) at 15 K have shown strong incre…

Single Dirac-cone on the Cs-covered topological insulator surface Sb2Te3(0001)

Christoph Seibel, Henriette Maaß, Minoru Ohtaka +6

Using angle-resolved photoelectron spectroscopy we investigate the surface electronic structure of the three-dimensional topological insulator (TI) Sb2Te3(0001). Our data show the…
