Paper Abstract
This work presents experimental evidence of giant electromechanical and electrothermal transduction under ferroelectric/ferroelectric rhombohedral-orthorhombic phase transformation. Combinations of stress, electric field and temperature drive a phase transformation from rhombohedral to orthorhombic in [110]cut and poled ferroelectric single crystals. This phase transformation is accompanied by a large jump in polarization and strain. The results indicate that the ferroelectric crystals produce significant electrical energy density per cycle. Electrical transduction properties are measured from mechanical and thermal excitations applied to a ternary Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 (PINPMN- PT) single crystal of composition just at the rhombohedral side of a morphotropic phase boundary. An overview of 32 mode phase transformation transduction characterization is discussed.
