点阵缺陷,晶格缺陷
The hydroxyl lattice defect was key factor to influence the phase transition from paraelectric cubic to ferroelectric tetragonal structure.
并发现羟基缺陷的减少是影响体系相转变的关键因素。
XRD results show shat, with the increase of Mg doping amount, the lattice defect of Mg: Mn: LiNbO_3 crystals are increase and then decrease when Mg doping amount is up to the threshold.
晶体的X射线衍射表明,Mg:Mn:LiNbO3晶体的晶格缺陷在掺镁量没有达到阈值浓度时,随掺镁量的增大而逐渐增大,当掺镁量达到阈值浓度时又有下降的趋势;
