Gate-tunable anomalous Hall effect in stacked van der Waals ferromagnetic insulator - topological insulator heterostructures
Andres E. Llacsahuanga Allcca, Xing-Chen Pan, Ireneusz Miotkowski +2
The search of novel topological phases, such as the quantum anomalous Hall insulator (QAHI) or the axion insulator, has motivated different schemes to introduce magnetism into topo…
Opposite current-induced spin polarizations in bulk-metallic Bi2Se3 and bulk-insulating Bi2Te2Se topological insulator thin flakes
Jifa Tian, Cüneyt Şahin, Ireneusz Miotkowski +2
One of the most fundamental and exotic properties of 3D topological insulators (TIs) is spin-momentum-locking (SML) of their topological surface states (TSSs), promising for potent…
Tuning insulator-semimetal transitions in 3D topological insulator thin films by inter-surface hybridization and in-plane magnetic fields
Yang Xu, Guodong Jiang, Ireneusz Miotkowski +2
A pair of Dirac points (analogous to a vortex-antivortex pair) associated with opposite topological numbers (with Berry phases) can be merged together through parameter tuni…
Gate-tunable supercurrent and multiple Andreev reflections in a superconductor-topological insulator nanoribbon-superconductor hybrid device
Luis A. Jauregui, Morteza Kayyalha, Aleksander Kazakov +3
We report on the observation of gate-tunable proximity-induced superconductivity and multiple Andreev reflections (MAR) in a bulk-insulating BiSbTeSe topological insulator nano…
Electrical spin injection into graphene from a topological insulator in a van der Waals heterostructure
Jifa Tian, Ting-Fung Chung, Ireneusz Miotkowski +1
All-electrical (magnetic-material-free) spin injection is one of the outstanding goals in spintronics. Topological insulators (TIs) have been recognized as a promising electrically…
Quantum transport of two-species Dirac fermions in dual-gated three-dimensional topological insulators
Yang Xu, Ireneusz Miotkowski, Yong P. Chen
Topological insulators are a novel class of quantum matter with a gapped insulating bulk yet gapless spin helical Dirac fermion conducting surface states. Here, we report local and…
