四种过渡金属氧化物SrTMO3(TM = Rh,Ti,Mo,Zr)在压力下物理性质的变化:从头算研究

摘要:

采用基于密度泛函理论的平面波赝势方法,利用第一性原理计算,在广义梯度近似(GGA)下研究了SrTMO3(TM = Rh,Ti,Mo,Zr)在压力作用下的结构和弹性性质.在零压下研究了其光学性质。结果表明,计算的晶格参数与已有的实验结果和以前的理论结果符合得很好。

英文摘要:

Using first principles calculations, we have studied the structural and elastic properties of SrTMO3 (TM = Rh, Ti, Mo, Zr) under pressure by the plane wave pseudopotential method based on the density functional theory (DFT) within the generalized gradient approximation (GGA). The optical properties have been investigated under zero pressure. It is observed that the calculated lattice parameters are in good agreement with the available experimental result and previous theoretical results.
