1) impurity and defect
杂质或缺陷态
2) impurity defects
杂质缺陷
1.
In contrast with the case of pure lithium niobate crystals,the H+ directly participant in defect complex and distribute very near the highly-charged impurity defects in highly magnesium-doped lithium niobate crystals,which causes the OH- absorption peak varies with changing temperature.
通过分析两种晶体中不同的缺陷模型以及H+在晶格中的占位,我们提出高掺镁铌酸锂晶体中的H+紧邻高电性杂质缺陷(MgNb)3-分布,直接参与缺陷集团,完全不同于纯铌酸锂晶体中H+的分布情形,这造成了高掺镁铌酸锂晶体中OH-振动吸收峰随温度的变化。
3) defect struchures
