Anomalous Piezoelectricity from Polarization-Dependent Electrostriction in Wurtzites
Guo-Dong Zhao, Aiden Ross, Yueze Tan +3
The piezoelectric coefficient is a third-rank tensor connecting the strain or stress with the electric field or polarization, whereas the electrostriction coefficient is a fourth-r…
Chemical heterogeneity at conducting ferroelectric domain walls
Kasper A. Hunnestad, Guo-Dong Zhao, Mao-Hua Zhang +7
Natural interfaces in ferroic oxides have developed into versatile playgrounds for studying electronic correlation effects in 2D systems. The microscopic origin of the emergent loc…
Emergent spin-resolved electronic charge density waves and pseudogap phenomena from strong -wave altermagnetism
Fei Yang, Guo-Dong Zhao, Binghai Yan +1
Inspired by recent discovery of metallic -wave altermagnetism in KVSeO, we develop a self-consistent microscopic many-body calculation of density-wave order for an itine…
Thermodynamic stabilization and electronic effects of oxygen vacancies at BiFeO neutral ferroelectric domain walls
Guo-Dong Zhao, Ismaila Dabo, Long-Qing Chen
Enhanced conductivity at ferroelectric domain walls in BiFeO has been widely observed, yet the microscopic origins of this effect, including electronic contributions from domai…
Flexocoupling-induced phonons and ferrons in van der Waals ferroelectrics
Anna N. Morozovska, Eugene. A. Eliseev, Oleksiy V. Bereznikov +7
The contribution of flexoelectric coupling to the long-range order parameter fluctuations in ferroics can be critically important to the ferron dispersion and related polar, pyroel…
