Gate-tunable anomalous Hall effect in a 3D topological insulator/2D magnet van der Waals heterostructure
Vishakha Gupta, Rakshit Jain, Yafei Ren +8
We demonstrate advantages of samples made by mechanical stacking of exfoliated van der Waals materials for controlling the topological surface state of a 3-dimensional topological…
Topological Phase Transitions in a Hybridized Three-Dimensional Topological Insulator
Su Kong Chong, Lizhe Liu, Taylor D. Sparks +2
As the thickness of a three-dimensional (3D) topological insulator (TI) becomes comparable to the penetration depth of the surface states, quantum tunneling between surfaces turns…
Landau Levels of Topologically-Protected Surface States Probed by Dual-Gated Quantum Capacitance
Su Kong Chong, Ryuichi Tsuchikawa, Jared Harmer +2
Spectroscopy of discrete Landau levels (LLs) in bulk-insulating three-dimensional topological insulators (3D TIs) in perpendicular magnetic field characterizes the Dirac nature of…
Tunable Coupling between Surface States of a Three-Dimensional Topological Insulator in the Quantum Hall Regime
Su Kong Chong, Kyu Bum Han, Taylor D. Sparks +1
The paired top and bottom Dirac surface states, each associated with a half-integer quantum Hall (QH) effect, and a resultant integer QH conductance (νe2/h), are hallmarks of a thr…
Topological Insulator-Based van der Waals Heterostructures for Effective Control of Massless and Massive Dirac Fermions
Su Kong Chong, Kyu Bum Han, Akira Nagaoka +8
Three dimensional (3D) topological insulators (TIs) are an important class of materials with applications in electronics, spintronics and quantum computing. With the recent develop…
