Elastic and electronic properties calculations of the filled skutterudite CeOs4P12

Abstract

The full-potential linear muffin-tin orbital method (FP-LMTO) within the local density approximation (LDA) using the Perdew-Wang parameterization is used to calculate the structural, electronic and elastic properties of the filled skutterudite CeOs4P12. The results of the electronic properties show that this compound is an indirect band gap material (T -N). A special interest has been made to the determination of the elastic constants since there have been no available experimental and theoretical data. The energy band gaps and their volume and pressure dependence are also investigated.
