Unconventional Josephson Effect in Hybrid Superconductor-Topological Insulator Devices [PDF]

open access: yes, 2012
We report on transport properties of Josephson junctions in hybrid superconducting-topological insulator devices, which show two striking departures from the common Josephson junction behavior: a characteristic energy that scales inversely with the width

Room temperature magnetization switching in topological insulator-ferromagnet heterostructures by spin-orbit torques

open access: yesNature Communications, 2017
The application of spin-orbit torque in topological insulator heterostructures is limited only under low temperature. Here, the authors report room temperature magnetization switching in topological insulator-ferromagnet heterostructures by spin-orbit ...

Non-equilibrium spin density and spin-orbit torque in three dimensional topological insulators - antiferromagnet heterostructure

open access: yes, 2019
We study the behavior of non-equilibrium spin density and spin-orbit torque in a topological insulator - antiferromagnet heterostructure. Unlike ferromagnetic heterostructures where Dirac cone is gapped due to time-reversal symmetry breaking, here the ...

Surface Diffusion in SnTe‐PbTe Monolayer Lateral Heterostructures

open access: yesAdvanced Functional Materials, EarlyView.
The lateral heterostructures between 2D materials often suffer from the interdiffusion at the interfaces. Here, a surface diffusion mechanism is found to be dominating at the interfaces between semiconducting SnTe and PbTe monolayers. Atomically sharp interfaces can be achieved by suppressing this diffusion process. ABSTRACT The construction of complex

Enhanced spin Seebeck effect signal due to spin-momentum locked topological surface states

open access: yesNature Communications, 2016
Future spintronic devices may exploit topological insulators, bulk insulators with unique spin-momentum locked conductive surface states. Here, the authors demonstrate the detection of thermally-generated spin currents in a ferromagnetic-insulator ...

Stacking‐Engineered Magnonic Topology and Transport in Honeycomb Homobilayers

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Topological magnons have emerged as a promising platform for dissipationless bosonic transport. However, a straightforward and effective strategy to engineer such topological states in real materials has yet to be fully realized. Here, a general scheme for controlling magnonic topological states via stacking engineering in van der Waals ...

Band gap of a topological insulator nanotube

open access: yesMoldavian Journal of the Physical Sciences, 2011
We study the electronic structure of a topological insulator Bi2Te3 cylindrical nanotube. The energy spectrum was calculated in the framework of the kp theory near the Γ point of the surface Brilloiun zone.
