• A computer simulation by a molecular dynamics method at constant volume hasbeen performed to a model system which is composed of accumulating two differenttonic conductors: I - =AgI-Ag.S-Agl-Ag.S- I -. Along the c-axis ((-axis), Agl-partsare compressed and Ag.S-parts are stretched. About 3% of Ag ions in Ag.S-partshave been transfered to Agl-parts. The self-diffusion coefficient of Ag ions in Agl-parts decreases by 40-50% compared with that in a single Agl-system, while the diffu-sion coefficient of Ag ions in Ag.S-parts increases by 30% compared with that in asingle Ag.S-system. The ionic conductivity of the superlattice-system is larger thanthat of either material of the Agl-system or Ag.S-system. The calculation suggests thepossibility of the existence of a new material which has a larger ionic conductivity.
