  1. 1. Femtosecond Photoemission Electron Microscopy of Indium Arsenide Nanowires

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Björn Johansson; [2018]
    Keywords : Indium Arsenide; PEEM; Femtosecond laser; Time-resolved PEEM; InAs; Wurtzite; zinc blende; pump-probe; Photoemission Electron Microscopy; pulsed laser.; Physics and Astronomy;

    Abstract : PhotoEmission Electron Microscopy (PEEM) has proven to be a successful method for examining the electronic characteristics of nanostructures. The experiments relevant for the following report were conducted using a combination of PEEM and a femtosecond pulsed laser to determine the electrical characteristics of Indium Arsenide nanowire of crystal structure varying between wurtzite and zinc blend.

  3. 2. Photoemission electron microscopy of localized surface plasmons in silver nanostructures: Experiments and simulations

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Robin Sutinen Svärd; [2015]
    Keywords : Photoemission electron microscopy; Localized surface plasmon; Ag nanocube; Ag nanoellipsoid; Finite-difference time-domain; Physics and Astronomy;

    Abstract : In this work, spatially resolved localized surface plasmons (LSPs) in individual silver nanocubes and nanoellipsoids are imaged with a photoemission electron microscope (PEEM). Using broadband laser pulses with photon energies below the work function threshold of the material, multiphoton photoemission (MPPE) processes coupled to the LSPs governs the strong enhancement of the plasmonic near-field detected in the PEEM.

  4. 3. Surface Studies on Industrial Aluminium Alloys

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Lisa Rullik; [2014]
    Keywords : aluminium alloy; heat treatment; XPS; XPEEM; Physics and Astronomy;

    Abstract : Aluminium alloys are used in a wide range of applications due to their high tensile strength concomitant with low density. Additionally, aluminium alloys form a naturally occurring and passivating oxide layer, which leads to high corrosion and weathering resistance. READ MORE

  5. 4. Scanning Tunneling Microscopy and Low-Energy Electron Diffraction Studies of Quantum Wires on Si(332)

    University essay from Karlstads universitet/Fakulteten för teknik- och naturvetenskap

    Author : Jörgen Gladh; [2006]
    Keywords : Physics;

    Abstract : In this master thesis I have investigated one-dimensional nanostructures, so called quantum wires. The goal was to grow them in situ on a stepped silicon surface and thereafter do several kinds of measurements, like Scanning Tunneling Microscopy, Low-Energy Electron Diffraction and Photoemission.
