Piezoelectric mimicry of flexoelectricity [PDF]
Physical Review Letters, 2018 The origin of "giant" flexoelectricity, orders of magnitude larger than theoretically predicted, yet frequently observed, is under intense scrutiny. There is mounting evidence correlating giant flexoelectric-like effects with parasitic piezoelectricity ...
