title: Electrical conductivity in patterned silver-mesoporous titania nanocomposite thin films: towards robust 3D nano-electrodes.
abstract: The space-resolved electrical conductivity of patterned silver nanoparticle (NP) arrays embedded in mesoporous TiO(2) thin films was locally evaluated using a conductive-tip AFM. A remarkable conductivity dependence on the film mesostructure and metal NP loading was observed, confirming a three-dimensional current flow throughout the nanocomposite.
