|Piezoelectric Single Crystal PMN-PT: Field-induced Actuation at Temperature|
|Keywords: electro-active, piezoelectric effect, single crystal|
|Advances in melt growth of single crystals have allowed for the development of low-loss, electro-active components for higher temperature and electric drive technologies in system of (x) Pb(Mg1/3Nb2/3)O3 - (1-x) PbTiO3 or PMN-PT. We report data for the converse piezoelectric effect, xjk=dijkEi, where applied field (E) induces strain (x) through the piezoelectric coefficient (d). Values are given for d333 as a function of temperature and titanium content ([Ti]). In additional, recent advances in moving transition temperatures to higher values by compositional substitution is reported for Pb(In1/2Nb1/2)O3-PMN-PT. Also, the compositional region between the triple point ([Ti]=1/4) and the morphotropic phase boundary ([Ti]=1/3) for PMN-PT is re-examined, in light of all the outstanding properties associated with this region.|
