摘    要:采用基于密度泛函理论的第一性原理方法,对不同Mn掺杂浓度的CeO2晶体结构进行了结构优化,分别计算了体相及掺杂后的晶胞参数,总能量,态密度和能带等.从理论上分析了Mn掺杂对CeO2晶体电子结构的影响,为CeO2材料的掺杂改性研究提供了理论依据.

关 键 词:CeO2  密度泛函理论  掺杂

Abstract:The geometry structure of CeO2 crystal was optimized in a series of Mn-doped cases by adopting the method of first principle based upon the density functional theory(DFT),and the parameters,total energy,density of states and band structure of the CeO2 and Mn-doping CeO2 were also studied.Mn-doping effects on electronic structure of CeO2 were analyzed,which provided a theoretical basis for the CeO2 material doping modification research.
Keywords:CeO2  density functional theory  doped
