Domain Wall-mediated Interfacial Ferroelectric Switching
Hao-Wen Xu, Wen-Cheng Fan, Jun-Ding Zheng +4
Interfacial ferroelectricity offers a promising platform for ultrafast, low-power memory devices. While previous studies have demonstrated the importance of domain wall in polariza…
Breathing ferroelectricity induced topological valley states in kagome niobium halide monolayers
Kai-Qi Wang, Jun-Ding Zheng, Wen-Yi Tong +1
In recent years, kagome lattices have garnered significant attention for their diverse properties in topology, magnetism, and electron correlations. However, the exploration of bre…
Machine learning exploration of topological polarization pattern in hexagonal boron nitride moiré superlattice
Jun-Ding Zheng, Cheng-Shi Yao, Song-Chuan Zhou +5
Twisted moiré supercells, which can be approximated as a combination of sliding bilayers and constitute various topologically nontrivial polarization patterns, attract extensive at…
Ferrovalley Physics in Stacked Bilayer Altermagnetic Systems
Yun-Qin Li, Yu-Ke Zhang, Xin-Le Lu +5
As an emerging magnetic phase, altermagnets with compensated magnetic order and non-relativistic spin-splitting have attracted widespread attention. Currently, strain engineering i…
