Abstract
A silver-ion diffusion in α-Te is investigated by a molecular-dynamics method introducing a polyhedron analysis. The microscopic picture for the diffusion process of silver ions is obtained by studying the ratio of the residence time of silver ions in octahedra, , to that in tetrahedra, . The temperature dependence of / is expressed as the Arrhenius formula with an activation energy of 0.18 eV.
