Pressure tunable quantum anomalous Hall states in a topological antiferromagnet
Su Kong Chong, Chao Lei, Jie Li +8
Mechanical modulation of the lattice parameter can modify the electronic structure and manipulate the magnetic coupling of a material without introducing impurities. Inspired by su…
Giant Hall Switching by Surface-State-Mediated Spin-Orbit Torque in a Hard Ferromagnetic Topological Insulator
Lixuan Tai, Haoran He, Su Kong Chong +17
Topological insulators (TI) and magnetic topological insulators (MTI) can apply highly efficient spin-orbit torque (SOT) and manipulate the magnetization with their unique topologi…
Proximity-induced quasi-one-dimensional superconducting quantum anomalous Hall state: a promising scalable top-down approach towards localized Majorana modes
Omargeldi Atanov, Wai Ting Tai, Ying-Ming Xie +14
In this work, ~100 nm wide quantum anomalous Hall insulator (QAHI) nanoribbons are etched from a two-dimensional QAHI film. One part of the nanoribbon is covered with superconducti…
Exchange-biased quantum anomalous Hall effect
Peng Zhang, Purnima P. Balakrishnan, Christopher Eckberg +12
The quantum anomalous Hall (QAH) effect is characterized by a dissipationless chiral edge state with a quantized Hall resistance at zero magnetic field. Manipulating the QAH state…
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…
