  1. 16. Modelling and simulation of plastic deformation on small scales : interface conditions and size effects of thin films

    Author : Per Fredriksson; Peter Gudmundson; Christian Niordson; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Strain gradient plasticity; Size effects; Thin films; Interface; Finite element method; Dislocations; Constitutive behaviour; Hardening behaviour; Indentation; Contact mechanics; Metal matrix composites; Engineering mechanics; Teknisk mekanik;

    Abstract : Contrary to elastic deformation, plastic deformation of crystalline materials, such as metals, is size-dependent. Most commonly, this phenomenon is present but unnoticed, such as the effect of microstructural length scales. READ MORE

  3. 18. Preparation and Properties of Surface Modified Thin Polymer Films

    Author : Sofia Kihlman Øiseth; Chalmers University of Technology; []
    Keywords : aminodextran; plasma polymerisation; polymer films; high-density polyethylene HDPE ; UV ozone treatment; surface modification; glow discharge plasma; in situ control; spin coating;

    Abstract : This thesis deals with preparation, modification and characterisation of thin polymer films. Most of the work has been performed using thin films of high-density polyethylene (HDPE) as a model system for systematic surface modifications by glow discharge plasma and UV/ozone treatments.

  4. 19. Metal Oxide Thin Films and Nanostructures Made by ALD

    Author : Mårten Rooth; Anders Hårsta; Jan-Otto Carlsson; Lauri Niinisö; Uppsala universitet; []
    Keywords : Inorganic chemistry; Atomic layer deposition; Metal oxide; Nanostructures; Template deposition; Thin films; Oorganisk kemi;

    Abstract : Thin films of cobalt oxide, iron oxide and niobium oxide, and nanostructured thin films of iron oxide, titanium oxide and multilayered iron oxide/titanium oxide have been deposited by Atomic Layer Deposition (ALD). The metal oxides were grown using the precursor combinations CoI2/O2, Fe(Cp)2/O2, NbI5/O2 and TiI4/H2O. READ MORE

  5. 20. Electrochromism in Nickel-based Oxides : Coloration Mechanisms and Optimization of Sputter-deposited Thin Films

    Author : Esteban Damián Avendaño Soto; Gunnar Niklasson; Andris Azens; Claes-Göran Granqvist; Ulf Helmersson; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Physics; Nickel based Oxide; Electrochromism; Thin Films; Sputtering; Coloration mechanism; Fysik; Physics; Fysik;

    Abstract : Electrochromic properties of sputter-deposited nickel-based oxide films have been studied with a two-fold goal. From a practical point of view, the optical switching performance has been improved by optimizing the deposition conditions and film stoichiometry with respect to oxygen and hydrogen, and further by adding Mg, Al, Si, Zr, Nb or Ta to the films.
