title: Synthesis, structure and ionic conductivity in nanopolycrystalline BaF2/CaF2 heterolayers.
abstract: Atomistic simulations have shown that the calculated conductivity of nano-polycrystalline BaF2/CaF2 heterolayers is considerably higher than the component bulk materials and we predict that grain-boundary diffusion is the key to fast ionic conductivity in these systems.
