  2. 2. Rare-gas Clusters Studied by Electron Spectroscopy Structure of Heterogeneous Clusters and Effects of Electron Scattering on Auger Decay

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Marcus Lundwall; Uppsala universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Nano-particles; Clusters; Heterogeneous clusters; Core-shell clusters; XPS; UPS; AES; Electron scattering; Radial structure; Surface structure; Surface sensitivity; Synchrotron radiation; Ne; Ar; Kr; Xe; Fysik;

    Sammanfattning : In this Thesis experimental studies of nano-clusters using synchrotron radiation based photoelectron (UPS and XPS) and Auger Electron Spectroscopy (AES) are presented. The investigations may be divided into two parts where the first reports on the structure of heterogeneous two component clusters, and the second concerns electronic decay processes. LÄS MER

  3. 3. ROLE OF SURFACE OXIDES IN SINTERING OF CHROMIUM-ALLOYED STEEL POWDER

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Henrik Karlsson; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water atomisation; surface analysis; sintering; chromium-alloyed steel.; Powder metallurgy; surface reactions; surface; surface oxide; SEM; XRD; AES; XPS;

    Sammanfattning : During water-atomisation and handling of steel powder the surface inevitably oxidises. The surface bound oxide is an important factor in the processing of powder metallurgical (PM) steels, especially in case the powder contains elements forming stable oxides, such as Cr, Mn, and Si.

  4. 4. Free Neutral Clusters and Liquids Studied by Electron Spectroscopy and Lineshape Modeling

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Henrik Bergersen; Uppsala universitet.; [2008]
    Nyckelord :Physics; Clusters; Nano-particles; XPS; UPS; AES; Radial structure; Molecular dynamics; Density functional theory; Liquids; Liquid microjet; Solvation; Fysik;

    Sammanfattning : The electronic and geometrical structure of free neutral clusters and liquids have been studied using synchrotron-radiation based photoelectron and Auger electron spectroscopy in combination with lineshape modeling. A novel experimental setup has been developed for studies of liquids, based on the liquid microjet technique. LÄS MER

  5. 5. Growth and Characterization of ZnO Nanocrystals

    Detta är en avhandling från Karlstad : Karlstads universitet

    Författare :Leif KE Ericsson; Karlstads universitet.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; ZnO; Nanocrystals; Surface physics; XPS; SEM; AES; AFM; STM; Physics; Fysik;

    Sammanfattning : The understanding of surfaces of materials is of crucial importance to all of us. Considering nanocrystals (NCs), that have a large surface to bulk ratio, the surfaces become even more important. Therefore, it is important to understand the fundamental surface properties in order to use NCs efficiently in applications. LÄS MER
