Atomistic Structure of Transient Switching States in Ferroelectric AlScN
Jiawei Huang, Jinyang Li, Xinyue Guo +5
We resolve the microscopic mechanism of polarization switching in wurtzite ferroelectric AlScN by integrating advanced thin-film fabrication, ferroelectric switching dynamics chara…

Unraveling Shear Strain Induced Ferroelectric-to-Antiferroelectric Phase Transition and Accessing Intrinsic Antiferroelectricity in Two-dimensional NbOCl2
Jiawei Mao, Yinglu Jia, Gaoyang Gou +2
Compared to the well studied two-dimensional (2D) ferroelectricity, much rare is the appearance of 2D antiferroelectricity, where local dipoles from the nonequivalent sublattices w…

Bonding relay for room-temperature oxide plasticity like metals
Xiangkai Chen, Yuhong Li, Xiaofei Zhu +2
Oxides have long been regarded as intrinsically brittle due to their strong, directional ionic or covalent bonds, in stark contrast to the ductile behavior of metals, where delocal…
