PMN-PT弛豫铁电单晶在过去的十年中被报道显示出优异的压电和介电性能。然而,Bridgman法生长的晶体的电学性能波动总是存在的。本文研究了PMN-32 PT单晶的压电、介电性能与元素分布的关系。结果表明,元素的分布是造成物性不均匀性的重要原因。PMN-32 PT晶体的d33随O的减少和Nb的增加而减小。PMN-32 PT晶体的介电性能敏感地依赖于Ti的异质性。
PMN-PT relaxor ferroelectric single crystals were reported to exhibit excellent piezoelectric and dielectric properties in the last decade. However, the fluctuation in electrical properties of the crystal grown by Bridgman technique always exists. The relationship between piezoelectric, dielectric properties and elements' distribution of PMN-32PT single crystals were studied in this work. Results indicated that elements' distribution were important origins to the property inhomogeneity. The d 33 of PMN-32PT crystals decreased with the decrease of O and the increase of Nb. The dielectric properties of PMN-32PT crystals depended sensitively upon the heterogeneous of Ti.
