Quantum Anomalous Hall Effect in Perfectly Compensated Collinear Antiferromagnetic Thin Films
Chao Lei, Olle Heinonen, R. J. McQueeney +1
We show that the quantum anomalous Hall effect almost always occurs in magnetic topological insulator thin films whenever the top and bottom surface layer magnetizations are parall…
Large Anomalous Hall Effect in Topological Insulators Proximitized by Collinear Antiferromagnets
Chao Lei, Hua Chen, Allan H. MacDonald
CrSb is an attractive material for room-temperature antiferromagnetic spintronic applications because of its high Néel temperature 700 K and semi-metallic character. We study…
Silicon Donor Array as a Disordered One-Dimensional Electron Gas
Chao Lei, Allan H. MacDonald
Donors in silicon can now be positioned with an accuracy of about one lattice constant, making it possible in principle to form donor arrays for quantum computation or quantum simu…
Metamagnetism of few layer topological antiferromagnets
C. Lei, O. Heinonen, A. H. MacDonald +1
MnBiTe (MBT) is a promising antiferromagnetic topological insulator whose films provide access to novel and technologically important topological phases, including quantum…
Gate-Tunable Quantum Anomalous Hall Effects in MnBiTe Thin Films
Chao Lei, Allan H. MacDonald
The quantum anomalous Hall (QAH) effect has recently been realized in thin films of intrinsic magnetic topological insulators (IMTIs) like MnBiTe. Here we point out that th…
