Sliding Flexoelectricity in Two-Dimensional van der Waals Systems
Ri He, Hua Wang, Fenglin Deng +5
Two-dimensional sliding ferroelectrics, with their unique stacking degrees of freedom, offer a different approach to manipulate polarization by interlayer sliding. Bending sliding…
A compositional ordering-driven morphotropic phase boundary in ferroelectric solid solutions
Yubai Shi, Yifan Shan, Hongyu Wu +3
Ferroelectric solid solutions usually exhibit giant dielectric response and high piezoelectricity in the vicinity of the morphotropic phase boundary (MPB), where the structural pha…
Ferroelastic twin wall mediated ferro-flexoelectricity and bulk photovoltaic effect in SrTiO
Ri He, Haowei Xu, Peijun Yang +3
Ferroelastic twin walls in nonpolar materials can give rise to a spontaneous polarization due to symmetry breaking. Nevertheless, the bi-stable polarity of twin walls and its rever…
Pressure-induced one-dimensional oxygen ion diffusion channel in lead-apatite
Ri He, Hongyu Wu, Xuejian Qin +2
Recently, Lee et al. claimed that the experimental observation of room-temperature ambient-pressure superconductivity in a Cu-doped lead-apatite (Pb10-xCux(PO4)6O). The study revea…
Origin of negative thermal expansion and pressure induced amorphization in zirconium tungstate from machine-learning potential
Ri He, Hongyu Wu, Yi Lu +1
Understanding various macroscopic pressure-volume-temperature properties of materials on the atomistic level has always been an ambition for physicists and material scientists. Par…
