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…
Sample-dependent Dirac point gap in MnBiTe and its response to the applied surface charge: a combined photoemission and ab initio study
A. M. Shikin, D. A. Estyunin, N. L. Zaitsev +16
Recently discovered intrinsic antiferromagnetic topological insulator MnBiTe presents an exciting platform for realization of the quantum anomalous Hall effect and a number…
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…
Band gap opening at the Dirac point in Co/BiSbTeSe2(0001) system
A. K. Kaveev, A. G. Banshchikov, A. N. Terpitskiy +6
Sub-angstrom Co coverage, being deposited on BiSbTeSe2(0001) surface at 200-330 C, opens a band gap at the Dirac point, with the shift of the Dirac point position caused by RT adso…
