摘要:

采用基于密度泛函理论的赝势平面波从头算方法,在广义梯度近似(GGA)下研究了压力对ScM(M = Rh,Cu,Ag,Hg)化合物结构和弹性性质的影响.在零压下研究了其光学性质。计算结果表明,优化后的晶格参数与实验数据和其它理论值吻合较好。

英文摘要:

The influence of pressure on the structural and elastic properties of ScM (M = Rh, Cu, Ag, Hg) compounds has been performed by using ab initio approach pseudopotential plane- wave method based on the density functional theory within the generalized gradient approximation (GGA). The optical properties have been investigated under zero pressure. It is found that the optimized lattice parameters for all metals are in good agreement with the experimental data and other available theoretical values.
