Chern insulator phase realized in dual-gate-tuned MnBi2Te4 thin films grown by molecular beam epitaxy
Yunhe Bai, Yuanzhao Li, Ruixuan Liu +19
The intrinsic magnetic order, large topological-magnetic gap and rich topological phases make MnBi2Te4 a wonderful platform to study exotic topological quantum states such as axion…
Interplay between electronic dephasing and localization in finite-sized Chern insulator
Yunhe Bai, Yuanzhao Li, Jianli Luan +14
Anderson localization is anticipated to play a pivotal role in the manifestation of the quantum anomalous Hall effect, akin to its role in conventional quantum Hall effects. The si…
Correlation between magnetic domain structures and quantum anomalous Hall effect in epitaxial MnBi2Te4 thin films
Yang Shi, Yunhe Bai, Yuanzhao Li +16
We use magnetic force microscopy (MFM) to study spatial uniformity of magnetization of epitaxially grown MnBi2Te4 thin films. Compared to films which exhibit no quantum anomalous H…
Reentrant quantum anomalous Hall effect in molecular beam epitaxy-grown MnBi2Te4 thin films
