    Porous-anodic-alumina-supported nanostructured Ta2O5/Ta films for advanced capacitors

  • Original language description

    An advanced approach is implemented to fabricate Ta2O5/Ta films with highly porous nanostructured morphology and substantially enlarged surface-to-volume ratio via electrochemical anodizing of tantalum layers sputter-deposited over the nanoporous alumina substrates. Potential application of the films as metal/oxide electrodes for electrolytic and thin-film capacitors
