Autor: K Sumida, M Kakoki, J Reimann, M Nurmamat, S Goto, Y Takeda, Y Saitoh, K A Kokh, O E Tereshchenko, J Güdde, U Höfer, A Kimura

Publikováno v: New Journal of Physics, Vol 21, Iss 9, p 093006 (2019)

Quantum anomalous Hall effect (QAHE) is a key phenomenon for low power-consumption device applications owing to its dissipationless spin-polarized and quantized current in the absence of an external magnetic field. However, the recorded working tempe

Publikováno v: New Journal of Physics, Vol 16, Iss 6, p 065016 (2014)

We have clarified that a topological insulator, Bi _2 Te _2 Se, shows two surface states with gigantic Rashba-type spin-splitting located at a binding energy deeper than the topological surface state. The magnitude of the Rashba parameter, as well as
