To investigate relation between inhomogeneous structure of Ag x (GeSe 3 ) 1-x superionic glass and conduction path formation, x-ray diffraction, neutron diffraction and EXAFS measurements on K-edges for each constituent were performed. Reverse Monte Carlo structural modelling based on these experimental data revealed that Ag conduction paths are formed in random glass media of GeSe 4 tetrahedral network. The first sharp diffraction peak (FSDP) located at 1.1 Å -1 is mainly contributed by GeSe 4
