Ab initio study of Cu diffusion in α-cristobalite

We have studied the geometries, formation energies, migration barriers and diffusion of a copper interstitial with different charge states with and without an external electric field in the α -cristobalite crystalline form of SiO _2 using ab initio computer simulation. The most stable state almost t...
