PERCOLATION PHENOMENA IN SR1-XCEXF2+X

摘要: The theory of random walks in barrier networks has been applied to describe the properties associated with hopping motion fluoride ions single crystals ${\mathrm{Sr}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$${\mathrm{Ce}}_{\mathrm{x}}$${\mathrm{F}}_{2+\mathrm{x}}$. It appears that theoretically predicted features like anomalous diffusion, leveling off mean-square displacement, and normal diffusion long-time limit can be observed for these crystals.
