  2. 6. Corrosion Behavior of Duplex Stainless Steels in Acidic-Chloride Solutions Studied with Micrometer Resolution

    Author : Marc Femenia; KTH; []
    Keywords : In situ; local dissolution; STM; SKPFM; MFM; SAES; duplex stainless steel; acidic-chloride solution;

    Abstract : The local corrosion behavior of duplex stainless steel (DSS)is affected by a wide variety of factors. Localized corrosionof DSS frequently starts at micrometer scale inclusions orprecipitates, which are often segregated in theaustenite-ferrite boundary regions. READ MORE

    Abstract : In this Ph.D. thesis I present the background and providefurther details to the work presented in the appended papers. The background consists of brief overviews of Kondo physics, Luttinger liquid theory, and conformal field theory. READ MORE

  5. 8. Titania Nanoscale Films and Surfaces : Surface Science Investigation of Structure and Properties

    Author : Davide Ragazzon; Anders Sandell; Anne Borg; Jason F. Weaver; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photoelectron spectroscopy; PES; XPS; scanning tunneling microscopy; STM; titania; titanium oxide; TiO2; Au 111 ; gold; water; H2O; rutile;

    Abstract : This thesis presents surface science studies, investigating several aspects of titanium dioxide at the atomic scale. The greater part of this work is devoted to the preparation by chemical vapor deposition (CVD) of titanium(IV) tetraisopropoxide (TTIP) of ultrathin TiO2 or TiOx films on Au(111). READ MORE

  6. 9. Scanning probe techniques as an investigation tool for semiconductor nanostructures and devices

    Author : Jovana Colvin; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; III-V semiconductors; AFM; STM; KPM; SCM; c-AFM; Crystal growth; Doping; Defects;

    Abstract : Semiconductor nanostructure based devices provide new opportunities for contributing to a sustainable energy usage. This includes harvesting of energy (solar cells) and saving of energy, e.g. in lighting (light-emitting diodes, LEDs) and transfer of energy (power devices). READ MORE

  7. 10. Scanning tunneling microscopy and photoemission studies of Ag films on metal/semiconductor surfaces

    Author : Samuel Starfelt; Hanmin Zhang; Lars Johansson; Anders Mikkelsen; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum well states; thin films; semiconductor; STM; STS; ARPES; Physics; Fysik;

    Abstract : The research presented in this thesis has been focused on the study of thin Ag films, grown on metal-reconstructed Si(111) and Ge(111) surfaces.The films have been grown at room temperature, and the morphologiesand electronic structures of the films have been investigated using scanning tunneling microscopy and spectroscopy (STM/STS), low-energy electron diffraction (LEED) and angle-resolved photoelectron spectroscopy(ARPES).
