Zero Poisson' s Ratio and Suppressed Mechanical Anisotropy in BP/SnSe Van der Waals Heterostructure: A First-principles Study
Qi Ren, Xingyao Wang, Yingzhuo Lun +2
Black phosphorene and its analogs have attracted intensive attention due to their unique puckered structures, anisotropic characteristics, and negative Poisson's ratio. The van der…
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…
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…
Thickness-dependent in-plane polarization and structural phase transition in van der Waals Ferroelectric CuInP2S6
Jianming Deng, Yanyu Liu, Mingqiang Li +7
Van der Waals (vdW) layered materials have rather weaker interlayer bonding than the intra-layer bonding, therefore the exfoliation along the stacking direction enables the achieve…
