Bulk topological insulators as inborn spintronics detectors
Y. Shiomi, K. Nomura, Y. Kajiwara +5
Detection and manipulation of electrons' spins are key prerequisites for spin-based electronics or spintronics. This is usually achieved by contacting ferromagnets with metals or s…
Unexpectedly robust protection from backscattering in the topological insulator BiSbTeSe
Sunghun Kim, Shunsuke Yoshizawa, Yukiaki Ishida +5
Electron scattering in the topological surface state (TSS) of the bulk-insulating topological insulator BiSbTeSe was studied using quasiparticle int…
Relationship between Fermi-Surface Warping and Out-of-Plane Spin Polarization in Topological Insulators: a View from Spin-Resolved ARPES
M. Nomura, S. Souma, A. Takayama +5
We have performed spin- and angle-resolved photoemission spectroscopy of the topological insulator Pb(Bi,Sb)2Te4 (Pb124) and observed significant out-of-plane spin polarization on…
Manipulation of Topological States and Bulk Band Gap Using Natural Heterostructures of a Topological Insulator
K. Nakayama, K. Eto, Y. Tanaka +5
We have performed angle-resolved photoemission spectroscopy on (PbSe)5(Bi2Se3)3m, which forms a natural multilayer heterostructure consisting of a topological insulator (TI) and an…
Unexpected mass acquisition of Dirac fermions at the quantum phase transition of a topological insulator
T. Sato, Kouji Segawa, K. Kosaka +6
The three-dimensional (3D) topological insulator is a novel quantum state of matter where an insulating bulk hosts a linearly-dispersing surface state, which can be viewed as a sea…
Spin Polarization of Gapped Dirac Surface States Near the Topological Phase Transition in TlBi(S1-xSex)2
S. Souma, M. Komatsu, M. Nomura +6
We performed systematic spin- and angle-resolved photoemission spectroscopy of TlBi(S1-xSex)2 which undergoes a topological phase transition at x ~ 0.5. In TlBiSe2 (x = 1.0), we re…
