Spin texture tunability in MnGeBiTe through varying Ge Concentration
A. M. Shikin, D. A. Estyunin, N. L. Zaitsev +10
The spin-resolved dispersion dependencies for the topological insulator MnGeBiTe in the path of the Brillouin zone were studied b…
Buildup and dephasing of Floquet-Bloch bands on subcycle time scales
S. Ito, M. Schüler, M. Meierhofer +10
Strong light fields have created spectacular opportunities to tailor novel functionalities of solids. Floquet-Bloch states can form under periodic driving of electrons and enable e…
Ultrafast electron dynamics in a topological surface state observed in two-dimensional momentum space
J. Reimann, K. Sumida, M. Kakoki +5
We study ultrafast population dynamics in the topological surface state of SbTe in two-dimensional momentum space with time- and angle-resolved two-photon photoemission. Li…
Electrically Controlled Spin Injection from Giant Rashba Spin-Orbit Conductor BiTeBr
Zoltán Kovács-Krausz, Anamul Md Hoque, Péter Makk +12
Ferromagnetic materials are the widely used source of spin-polarized electrons in spintronic devices, which are controlled by external magnetic fields or spin-transfer torque metho…
In situ tuning of symmetry-breaking induced non-reciprocity in giant-Rashba semiconductor BiTeBr
Mátyás Kocsis, Oleksandr Zheliuk, Péter Makk +8
Non-reciprocal transport, where the left to right flowing current differs from the right to left flowing one, is an unexpected phenomenon in bulk crystals. BiTeBr is a non-centrosy…
Probing topological insulators surface states via plasma-wave Terahertz detection
Leonardo Viti, Dominique Coquillat, Antonio Politano +7
Topological insulators (TIs) represent a novel quantum state of matter, characterized by edge or surface-states, showing up on the topological character of the bulk wave functions.…

We experimentally investigate Andreev transport through a single junction between an s-wave indium superconductor and a thick film of a three-dimensional topological ins…
Shubnikov-de Haas oscillations in p and n-type topological insulator (BiSb)Te
Ryota Akiyama, Kazuki Sumida, Satoru Ichinokura +4
We show Shubnikov-de Haas oscillations in topological insulator (BiSb)Te films whose carrier type is p-type (x = 0.29, 0.34) and n-type (x = 0.42). The ph…
Single electron gating of topological insulators
