  7. 5. Electrical Transport in Nanoparticle Thin Films of Gold and Indium Tin Oxide

    Author : Jesper Ederth; Knut Deppert; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Electrical transport; Nanoparticle; Nanocrystalline; Materialvetenskap; Materials science; Teknisk materialvetenskap; English; engelska;

    Abstract : Electrical transport properties of nanoparticle gold films made by the gas evaporation method were analysed using resistivity measurements. Low temperature electrical transport measurements showed a cross-over from a temperature range dominated by inelastic scattering to a temperature range dominated by elastic scattering, presumably by grain boundaries.
