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…
