Interplay between surface Dirac and Rashba states specific for topologically nontrivial van der Waals superlattices
I. A. Shvets, E. V. Chulkov, S. V. Eremeev
Here we show that, in contrast to the observed surface states in well studied pnictogen chalcogenide van der Waals (vdW) topological insulators (TIs) with quintuple layer (QL) or s…
On the floating of the topological surface state on top of a thick lead layer: The case of the Pb/Bi2Se3 interface
Oreste De Luca, Igor A. Shvets, Sergey V. Eremeev +9
The puzzling question about the floating of the topological surface state on top of a thick Pb layer, has now possibly been answered. A study of the interface made by Pb on Bi2Se3…
New spin-polarized electron source based on alkali-antimonide photocathode
V. S. Rusetsky, V. A. Golyashov, S. V. Eremeev +6
New spin-dependent photoemission properties of alkali antimonide semiconductor cathodes are predicted based on the detected optical spin orientation effect and DFT band structure c…
Topological magnetic materials of the (MnSbTe)(SbTe) van der Waals compounds family
S. V. Eremeev, I. P. Rusinov, Yu. M. Koroteev +6
Combining robust magnetism, strong spin-orbit coupling and unique thickness-dependent properties of van der Waals crystals could enable new spintronics applications. Here, using de…
Nature of the Dirac gap modulation and surface magnetic interaction in axion antiferromagnetic topological insulator MnBiTe
A. M. Shikin, D. A. Estyunin, I. I. Klimovskikh +18
Modification of the gap at the Dirac point (DP) in antiferromagnetic (AFM) axion topological insulator MnBiTe and its electronic and spin structure has been studied by angl…
Variety of magnetic topological phases in the (MnBiTe)(BiTe) family
I. I. Klimovskikh, M. M. Otrokov, D. Estyunin +23
Quantum states of matter combining non-trivial topology and magnetism attract a lot of attention nowadays; the special focus is on magnetic topological insulators (MTIs) featuring…
