Prediction and observation of the first antiferromagnetic topological insulator
Mikhail M. Otrokov, Ilya I. Klimovskikh, Hendrik Bentmann +41
Magnetic topological insulators (MTIs) are narrow gap semiconductor materials that combine non-trivial band topology and magnetic order. Unlike their nonmagnetic counterparts, MTIs…
Quantum spin Hall insulators in centrosymmetric thin films composed from topologically trivial BiTeI trilayers
I. A. Nechaev, S. V. Eremeev, E. E. Krasovskii +2
The quantum spin Hall insulators predicted ten years ago and now experimentally observed are instrumental for a breakthrough in nanoelectronics due to non-dissipative spin-polarize…
Ab initio lattice dynamics and electron-phonon coupling of Bi(111)
M. Alcántara Ortigoza, I. Yu. Sklyadneva, R. Heid +4
We present a comprehensive ab initio study of structural, electronic, lattice dynamical and electron-phonon coupling properties of the Bi(111) surface within density functional per…
One-dimensional potential for image-potential states on graphene
P. L. de Andres, P. M. Echenique, D. Niesner +2
In the framework of dielectric theory the static non-local self-energy of an electron near an ultra-thin polarizable layer has been calculated and applied to study binding energies…
Magnetic proximity effect in the 3D topological insulator/ferromagnetic insulator heterostructure
V. N. Men'shov, V. V. Tugushev, S. V. Eremeev +2
We theoretically study the magnetic proximity effect in the three dimensional (3D) topological insulator/ferromagnetic insulator (TI/FMI) structures in the context of possibility t…
Magnetic proximity effect at the 3D topological insulator/magnetic insulator interface
S. V. Eremeev, V. N. Men'shov, V. V. Tugushev +2
The magnetic proximity effect is a fundamental feature of heterostructures composed of layers of topological insulators and magnetic materials since it underlies many potential app…
