Flexoelectric Fracture-Ratchet Effect in Ferroelectrics [PDF]
Physical Review Letters, 2019 The propagation front of a crack generates large strain gradients and it is therefore a strong source of gradient-induced polarization (flexoelectricity). Herein, we demonstrate that, in piezoelectric materials, a consequence of flexoelectricity is that crack propagation is helped or hindered depending on whether it is parallel or antiparallel to the ...

Analog modulation by the flexoelectric effect in liquid crystals [PDF]
Applied Optics, 2020 We have solved the long-standing problems of stability and hysteresis, and we are able to obtain the homogeneous uniform lying helix structure in polymer-free cholesteric liquid crystals. This is instrumental for the present work to demonstrate the analog modulation at high speed and high precision.
