  1. 1. Competing phases of matter: Experimental spectroscopy study of the transition metal dichalcogenides Fe-doped TaS2 and Cu-intercalated TiSe2

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Christian Stefan Gruber; [2023]
    Keywords : Condensed matter physics; transition metal dichalcogenides; photoemission spectroscopy;

    Abstract : Syftet med denna avhandling är att bidra till forskningen av befintliga TMD:er (på Engelska transition metal dichalcogenide-TMD) som visar laddningstäthetsvågor och supraledning vid låga temperaturer (som 2H-TaS2). 2H-TaS2 är också känt för att visa supraledning vid 2K. READ MORE

    Keywords : Physics and Astronomy;

    Abstract : The Bloch beamline on 1.5 GeV ring at MAX IV Laboratory is dedicated to measure electronic structure of materials using the technique angle resolved photoelectron spectroscopy (ARPES) and spin resolved photoelectron spectroscopy (spin-ARPES). READ MORE

  4. 4. Real-time Entanglement of Auger and XPS-electrons: a preliminary investigation

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Philip Johansson; [2019]
    Keywords : Entanglement; Auger; Auger decay; photoemission; XPS; ED; exact diagonalization; Physics and Astronomy;

    Abstract : In this work, we employ a semi-classical approach to light matter interaction to describe and char- acterize spin configurations resulting from quantum correlations between electrons created by a photoemission event and by the following Auger decay. The system studied consists of three atomic levels and two continua. READ MORE

  5. 5. 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.
