First-principles calculation on the electronic structure and optical properties of the cubic inverse perovskite Sc3AlN
摘要
Abstract
The electronic structure and optical properties of the cubic inverse perovskite Sc3AlN have been calculated by using the first-principle density function theory molecular dynamics method. The results of band structure show that Sc3AlN is a conductor material. The complex dielectric functions, refractive index, reflection spectra, absorption spectra, optical conductivity and energy loss function of Sc3AlN are analyzed in terms of calculated band structure and density of state. The conduction band of Sc3AlN is mainly composed of Sc 3d, 4s and the valence bands is composed of the Al 2s, 2p and N 2p. The static dielectric function ε (0)=22.1, the reflectivity n(0)=4.7.关键词
