Kagome quantum anomalous Hall effect with high Chern number and large band gap
Zhen Zhang, Jing-Yang You, Xing-Yu Ma +2
Due to the potential applications in the low-power-consumption spintronic devices, the quantum anomalous Hall effect (QAHE) has attracted tremendous attention in past decades. Howe…
Voting Data-Driven Regression Learning for Discovery of Functional Materials and Applications to Two-Dimensional Ferroelectric Materials
Xing-Yu Ma, Hou-Yi Lyu, Xue-Juan Dong +4
Regression machine learning is widely applied to predict various materials. However, insufficient materials data usually leads to a poor performance. Here, we develop a new voting…
Great enhancement of Curie temperature and magnetic anisotropy in two-dimensional van der Waals magnetic semiconductor heterostructures
Xuejuan-Dong, Jingyang-You, Zheng Zhang +2
In two-dimensional (2D) magnetic systems, large magnetic anisotropy is needed to stabilize the magnetic order according to Mermin-Wagner theorem. Based on density functional theory…
