Defect Chemistry of Stronitum Titanate
-
摘要: 系統分析了有關SrTiO3的缺陷化學的文獻報道,在此基礎上給出了未摻雜、受主和施主摻雜SrTiO3的缺陷反應方程、平衡常數、各種缺陷的生成自由能和生成焓.由此可以計算和預測SrTiO3主要點缺陷的濃度.Abstract: Equilibrium constants of defect reactions, Gibbs free energies and formation enthalpies of defects in undoped, acceptor-doped and donor-doped SrTiO3 are presented on the bases of analysis of defect chemistry and corresponding reports. Thus, the concentration of point defects of the SrTiO3 can be calculated and predicted.
