Simultaneous Large Optical and Piezoelectric Effects Induced by Domain Reconfiguration Related to Ferroelectric Phase Transitions

Advanced Materials, Volume 34, Issue 7, February 17, 2022., 2022
In domain‐engineered relaxor ferroelectric crystals of Pb(In1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3, reversible and repeatable phase transitions from the as‐poled polydomain rhombohedral state to a monodomain monoclinic state can be stimulated by electric field or stress. These transitions lead to bimodal functionality—variable optical transparency as well
