The phonon properties of CoSb(2) have been investigated by Raman scattering spectroscopy and lattice dynamics calculations. Sixteen out of eighteen Raman active modes predicted by factor-group analysis are experimentally observed and assigned. The calculated and measured phonon energies at the Γ point are in very good agreement. The temperature dependence of the A(g) symmetry modes is well represented by phonon-phonon interactions without contribution from any other phonon or electron related interactions.
通过拉曼散射光谱学和晶格动力学计算研究了 CoSb(2) 的声子性质。通过因子群分析预测的 18 个拉曼活性模式中有 16 个被实验观察到并进行了归属。Γ 点处计算和测量的声子能量非常吻合。A(g) 对称模式的温度依赖性很好地由声子-声子相互作用表示，而没有来自任何其他声子或电子相关相互作用的贡献。
