Structural modification of nanocrystalline ceria by ion beams

摘要: Exceptional size-dependent electronic–ionic conductivity of nanostructured ceria can significantly alter materials properties in chemical, physical, electronic and optical applications. Using energetic ions, we have demonstrated effective modification interface volume grain size nanocrystalline from a few nm up to ∼25 nm, which is the critical region for controlling material property. The increases follows an exponential law as function ion fluence that with temperature, while cubic phase stable under irradiation. unique self-healing response radiation damage at boundaries utilized control nanoscale. Structural by ions proposed achieve desirable conductivity.
