Abstract

The electric field induced strain, piezoelectric and electromechanical response in relaxor based single crystal piezoelectrics (1-x)Pb(Mg 1/3Nb2/3)O3-xPbTiO3(PMNT100x) were investigated as a function of dc bias and temperature along the crystallographic [001] orientation. With increasing temperature and dc bias, monoclinic and rhombohedral phases were found to coexist in the crystals, exhibiting large strain hysteresis, while above a threshold temperature and dc bias, the induced monoclinic and tetragonal phases were found to show very low strain hysteresis. The electric field level for the monoclinic to tetragonal phase transformation was found to exponentially decay with temperature. The mechanical quality factor Q for the tetragonal phase exhibits higher values when compared to rhombohedral and monoclinic phases, displaying improved domain stability. The domain stability of tetragonal crystals as a function of sample thickness was also studied, it was found that a higher dc bias was needed for thinner tetragonal crystals in order to stabilize the single domain configuration and reduce the strain hysteresis.
