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

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

    Sammanfattning : 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.

  5. 4. Transparent Conductive Tin Doped Indium Oxide : Characterisation of Thin Films Made by Sputter Deposition with Silver Additive and by Spin Coating from Nanoparticle Dispersions

    Författare :Annette Hultåker; Peter van Nijnatten; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : Thin films of tin doped indium oxide (ITO) were prepared by two different methods: by sputter deposition with silver additive and by spin coating of a nanoparticle dispersion.ITO films doped with ≤ 20 at% of silver were prepared either as homogenous blends of ITO and silver or as intermixed layers.

  7. 5. Modification of Oxide Surfaces with Functional Organic Molecules, Nanoparticles, and Hetero-Oxide Layers

    Författare :Shilpi Chaudhary; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2015:Chaudhary;

    Sammanfattning : The research work described in this thesis is concerned with the modification of oxide surfaces, as reflected by its title. The surfaces and their modification have been studied using a range of experimental surface characterization tools, in particular x-ray photoelectron spectroscopy (XPS), fluorescence microscopy, scanning electron microscopy, atomic force microscopy, and scanning tunneling microscopy.
