  1. 1. A Quantum Chemical Investigation of Chemical Vapour Deposition of Fe using Ferrocene and Plasma Electrons

    Master-uppsats, Linköpings universitet/Kemi

    Författare :Felicia Andersson; [2023]
    Nyckelord :Quantum chemistry; Ferrocene; Silver; Ag 111 ; Plasma electrons; Surface chemistry; Electronic structure; DFT; Kvantkemi; Ferrocen; Silver; Ag 111 ; Plasmaelektroner; Ytkemi; Elektronstruktur; DFT;

    Sammanfattning : Thin films provide a remarkable asset, as depositing a thin surface layer can completely alter a material’s characteristics and provide new, inexpensive, and valuable properties. In 2020, a new Chemical Vapour Deposition (CVD) approach was developed at Linköping University, using plasma electrons as reducing agents for the deposition of metallic thin films. LÄS MER

  3. 2. Ultra-Thin Ag Films on the Sn/Si(111)-√3×√3 Surface Studied by STM

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Rasmus Lavén; [2018]
    Nyckelord :Silver; Silicon; Tin; Metal-semiconductor interfaces; Thin metal films; Scanning tunneling microscopy; Quantum size effects;

    Sammanfattning : The growth of atomically flat silver films on Si(111) usually requires a two-step growth, including deposition at low temperature (≈100 K) followed by slowly annealing to room temperature. In addition, flat silver films are usually only obtained on Si(111) for film thicknesses larger than the critical thickness of 6 monolayer. LÄS MER

  4. 3. Iron Oxide Thin Film Growth On Ag(100)

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Sara Ataran; [2014]
    Nyckelord :Surface Science; Material Science; XPS X-Ray Photoelectron Spectroscopy ; STM Scaning Tunneling Microscopy ; LEED Low Energy Electron Diffraction ; Science General;

    Sammanfattning : This thesis presents a study of iron oxide thin films, grown on a silver metal substrate, with the goal of characterizing the structures that form during growth of the first atomic layers. Such ultra-thin iron oxides are interesting model materials for fundamental surface chemistry and catalysis studies. LÄS MER

  5. 4. Computational Study of the Diffusion of Dehalogenated Molecules on a Ag(111) Surface

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi; Linköpings universitet/Tekniska högskolan

    Författare :Mohammed Rashed; [2014]
    Nyckelord :Dffusion;

    Sammanfattning : In this diploma work the diffusion of dehalogenated organic molecules on a metal surface was studied. More specifically the benzene tri-radical (BTR) on Ag(111) surfaces has been computationally studied using density functional theory calculations. LÄS MER

  7. 5. X-Ray Photoelectron Spectroscopy Study of Styrene Oxidation

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Niclas Johansson; [2010]
    Nyckelord :Styrene; Pt 111 ; XPS; FeO; Sljus; Physics and Astronomy;

    Sammanfattning : Silver has been proved as a heterogeneous catalyst for styrene epoxidation via detection of reaction fragments. After dosing styrene to the surface, reaction fragments were identified by comparing with literature values. The fragments were the oxametallacycle of styrene, carboxylic groups, benzene, and carbon residuals. LÄS MER
