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
Yuanzhao Li, Yunhe Bai, Yang Feng +16
In this study, we investigate intrinsic magnetic topological insulator MnBi2Te4 thin films grown by molecular beam epitaxy. We observe a reentrant quantum anomalous Hall effect whe…
Quantized anomalous Hall resistivity achieved in molecular beam epitaxy-grown MnBi2Te4 thin films
Yunhe Bai, Yuanzhao Li, Jianli Luan +17
The intrinsic magnetic topological insulator MnBi2Te4 provides a feasible pathway to high temperature quantum anomalous Hall (QAH) effect as well as various novel topological quant…
Tunable Dirac points and zero-energy modes in periodic curved graphene superlattices
Jianli Luan, Kaiyi Guo, Shangyang Li +3
We combined periodic ripples and electrostatic potentials to form curved graphene superlattices and studied the effects of space-dependent Fermi velocity induced from curvature on…
near new Dirac points in graphene superlattice
Jianli Luan, Shangyang Li, Tianxing Ma +1
New Dirac points appear when periodic potentials are applied to graphene, and there are many interesting effects near these new Dirac points. Here we investigate the $\textit{Zitte…
