当电介质内的不均匀区域达到纳米级时,纳米尺度效应对介电性能的影响便不容忽视.分别以PMN-PT弛豫铁电单晶、ZnO压敏陶瓷、纳米SiO_2/环氧树脂复合材料为例,通过实验证明了在无机铁电单晶、半导体陶瓷以及无机纳米/有机复合材料中存在的介电性能的纳米尺寸效应.
噹電介質內的不均勻區域達到納米級時,納米呎度效應對介電性能的影響便不容忽視.分彆以PMN-PT弛豫鐵電單晶、ZnO壓敏陶瓷、納米SiO_2/環氧樹脂複閤材料為例,通過實驗證明瞭在無機鐵電單晶、半導體陶瓷以及無機納米/有機複閤材料中存在的介電性能的納米呎吋效應.
당전개질내적불균균구역체도납미급시,납미척도효응대개전성능적영향편불용홀시.분별이PMN-PT이예철전단정、ZnO압민도자、납미SiO_2/배양수지복합재료위례,통과실험증명료재무궤철전단정、반도체도자이급무궤납미/유궤복합재료중존재적개전성능적납미척촌효응.
The nanoscale effects can not be ignored when the nanoscale inhomogeneous region exists in the dielectric materials. In order to confirm this effect in the inorganic ferroelectrics single crystals, semiconductor ceramics and inorganic/organic nanocomposites, the dielectric properties of PMN-PT single crystals, ZnO varistors and SiO_2/epoxy nanocomposites are measured and investigated.
