Correlation between electric-field-induced phase transition and piezoelectricity in lead zirconate titanate films [PDF]

, 2014
We observed that electric field induces phase transition from tetragonal to rhombohedral in polycrystalline morphotropic lead zirconate titanate (PZT) films, as reported in 2011 for bulk PZT.
