Giant Polarization and Abnormal Flexural Deformation in Bent Freestanding Perovskite Oxides
Songhua Cai, Yingzhuo Lun, Dianxiang Ji +15
Recent realizations of ultrathin freestanding perovskite oxides offer a unique platform to probe novel properties in two-dimensional oxides. Here, we observed a giant flexoelectric…
Conductive Domain Walls in Non-Oxide Ferroelectrics Sn2P2S6
Jianming Deng, Xingan Jiang, Yanyu Liu +11
The conductive domain wall (CDW) is extensively investigated in ferroelectrics, which can be considered as a quasi-two-dimensional reconfigurable conducting channel embedded into a…
Domain evolution in bended freestanding BaTiO3 ultrathin films: a phase-field simulation
Changqing Guo, Guohua Dong, Ziyao Zhou +4
Perovskite ferroelectric oxides are usually considered to be brittle materials, however, recent work [Dong et al., Science 366, 475 (2019)] demonstrated the super-elasticity in the…
Screening piezoelectricity in determination of flexoelectric coefficient at nanoscale
Yingzhuo Lun, Hao Zhou, Di Yao +2
Piezoelectricity usually accompanies with flexoelectricity in polar materials which is the linear response of polarization to a strain gradient. Therefore, it is hard to eliminate…
Ferroelastic switching with van der Waals direction transformation in layered PdSe2 driven by uniaxial and shear strain
Peng Lv, Gang Tang, Yanyu Liu +3
Uniaxial and biaxial strain approaches are usually implemented to switch the ferroelastic states, which play a key role in the application of the ferroics and shape memory material…
