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…
Analytical method to determine flexoelectric coupling coefficient at nanoscale
Hao Zhou, Yongmao Pei, Jiawang Hong +1
Flexoelectricity is defined as the coupling between strain gradient and polarization, which is expected to be remarkable at nanoscale. However, measuring the flexoelectricity at na…
Electric-field-tunable mechanical properties of relaxor ferroelectric single crystal measured by nanoindentation
Hao Zhou, Yongmao Pei, Faxin Li +2
Electric field dependent mechanical properties of relaxor ferroelectric material Pb(Mn1/3Nb2/3)O3-PbTiO3 are investigated with the nanoindentation technique. Giant electric-field-t…
Multi-field nanoindentation apparatus for measuring local mechanical properties of materials in external magnetic and electric fields
Hao Zhou, Yongmao Pei, Hu Huang +3
Nano/micro-scale mechanical properties of multiferroic materials can be controlled by the external magnetic or electric field due to the coupling interaction. For the first time, a…
External uniform electric field removing flexoelectric effect in epitaxial ferroelectric thin films
Hao Zhou, Jiawang Hong, Yihui Zhang +3
Using the modified Landau-Ginsburg-Devonshire thermodynamic theory, it is found that the coupling between stress gradient and polarization, or flexoelectricity, has significant eff…
Flexoelectricity induced increase of critical thickness in epitaxial ferroelectric thin films
Hao Zhou, Jiawang Hong, Yihui Zhang +3
Flexoelectricity describes the coupling between polarization and strain/stress gradients in insulating crystals. In this paper, using the Landau-Ginsburg-Devonshire phenomenologica…
