Research Abstract

A protonic conductor, which exhibits a high protonic conductivity at high temperature, was investigated from the structural aspects. The conducting proton was observed by means of neutron structure analyses and the migration path has been revealed. The proton migrates via neighboring proton sites showing a two-dimensional characteristic. Furthermore, there found a semistable site between the neighboring proton sites through which the protons are considered to move to the neighboring sites rather than directly jump to the ones.
