Electronic structure of Ag₈GeS₆

For the first time, the energy band structure, total and partial densities of states of Ag₈GeS₆ crystal were calculated using the ab initio density functional method in LDA and LDA+U approximations. Argyrodite is a direct-gap semiconductor with the calculated band gap width Eᵍᵈ = 1.46 eV in the LDA+...

description For the first time, the energy band structure, total and partial densities of states of Ag₈GeS₆ crystal were calculated using the ab initio density functional method in LDA and LDA+U approximations. Argyrodite is a direct-gap semiconductor with the calculated band gap width Eᵍᵈ = 1.46 eV in the LDA+U approximation. The valence band of argyrodite contains four energy-separated groups of occupied subzones. The unique feature of the electron-energy structure of Ag₈GeS₆ crystal is the energy overlapping between the occupied d-states of Ag atoms and the delocalized valence p-states of S atoms in relatively close proximity to the valence band top.
