Continuously control of polarization via electrically driven long-distance superlubric sliding
Peiyao Shi, Menghao Wu
Sliding ferroelectricity widely exists in various van der Waals bilayers or multilayers, which is induced by asymmetric stacking of commensurate interface. The greatly reduced swit…
Symmetry-engineering ferroelectricity in silicon dioxides
Yin Dai, Menghao Wu
It is a long-established rule for classical ferroelectricity that any ferroelectric crystal must adopt one of the 10 specific polar point groups. Here we predict a unique type of f…
An Inorganic Liquid Crystalline Dispersion with 2D Ferroelectric Moieties
Ziyang Huang, Zehao Zhang, Rongjie Zhang +11
Electro-optical effect based liquid crystal devices have been extensively used in optical modulation techniques, in which the Kerr coefficient reflects the sensitivity of the liqui…
Superlubric sliding ferroelectricity
Zihao Yang, Menghao Wu
Sliding ferroelectricity may emerge in many van der Waals bilayers/multilayers and the low switching barriers render ultrafast data writing with low energy cost. We note that such…
Ubiquitous van der Waals altermagnetism with sliding/moire ferroelectricity
Yuxuan Sheng, Junwei Liu, Jia Zhang +1
According to the recent studies on sliding/moire ferroelectricity, most 2D van der Waals nonferroelectric monolayers can become ferroelectric via multilayer stacking. In this paper…
Two-dimensional Topological Ferroelectric Metal with Giant Shift Current
Liu Yang, Lei Li, Zhi-Ming Yu +2
The pursuit for "ferroelectric metal" which combines seemingly incompatible spontaneous electric polarization and metallicity, has been assiduously ongoing but remains elusive. Unl…
Selective and Quasi-continuous Switching of Ferroelectric Chern Insulator Device for Neuromorphic Computing
Moyu Chen, Yongqin Xie, Bin Cheng +11
Topologically protected edge state transport in quantum materials is dissipationless and features quantized Hall conductance, and shows great potential in highly fault-tolerant com…
Unveiling the origin of unconventional moire ferroelectricity
Ruirui Niu, Zhuoxian Li, Xiangyan Han +13
Interfacial ferroelectricity emerges in heterostructures consisting of nonpolar van der Waals (vdW) layers, greatly expanding the scope of two dimensional ferroelectrics. In partic…
Ferroelectricity in crystals with non-polar point groups
Yuxuan Sheng, Menghao Wu
Ferroelectric crystals must adopt one of the 10 polar point groups according to the Neumann's principle. In this paper we propose that this conclusion is based on perfect bulk crys…
