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…
Highly skewed current-phase relation in superconductor-topological insulator-superconductor Josephson junctions
Morteza Kayyalha, Aleksandr Kazakov, Ireneusz Miotkowski +3
Three-dimensional topological insulators (TI's) in proximity with superconductors are expected to exhibit exotic phenomena such as topological superconductivity (TSC) and Majorana…
Anomalous low-temperature enhancement of supercurrent in topological-insulator nanoribbon Josephson junctions: evidence for low-energy Andreev bound states
Morteza Kayyalha, Mehdi Kargarian, Aleksandr Kazakov +5
We report anomalous enhancement of the critical current at low temperatures in gate-tunable Josephson junctions made from topological insulator BiSbTeSe nanoribbons with superc…
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…
