  1. 1. Electronic Structure Studies Using Resonant X-ray and Photemission Spectroscopy

    Author : Martin Magnuson; D D Sarma; Uppsala University; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Electronic structure; resonant x-ray emission; photoemission spectroscopy; Physics; Fysik;

    Abstract : This thesis addresses the electronic structure of molecules and solids using resonant X-ray emission and photoemission spectroscopy. The use of monochromatic synchrotron radiation and the improved performance of the instrumentation have opened up the possibility of detailed analyses of the response of the electronic systems under interaction with X-rays.

  2. 2. Core Level Spectroscopy of Water and Ice

    Author : Dennis Nordlund; Anders Nilsson; Martin Wolf; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; x-ray adsorption spectroscopy; photoemission spectroscopy; x-ray photoelectron spectroscopy; platinum; x-ray emission spectroscopy; density functional theory; hydrogen-bonded; H-bond; water; ice; electronic structure; excited state dynamics; proton dynamics; water adsorption; liquid water; Physics; Fysik;

    Abstract : A core level spectroscopy study of ice and water is presented in this thesis. Combining a number of experiments and spectrum calculations based on density functional theory, changes in the local valence electronic structure are shown to be sensitive to the local H-bonding configurations.

  3. 3. An X-ray Spectroscopic Study of Perovskites Oxides and Halides for Emerging Devices

    Author : Dibya Phuyal; Olof Karis; Manuel Bibes; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; perovskite oxides; halide perovskites; x-ray spectroscopy; electronic structure; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : This thesis investigates the electronic structures on several perovskite oxide and halide materials with a focus on light harvesting applications. The systematic study of the electronic properties of the transition metal oxides and post-transition metal halides is a key point if one is to understand their properties. READ MORE

  4. 4. Dynamics of optical and X-ray responses of molecules

    Author : Alexander Baev; KTH; []
    Keywords : two-photon absorption; collisional dephasing; resonant photoemission;

    Abstract : The aim of this licentiatethesis is to investigate by means of theoretical simulationsthe dynamics of light scattering by molecules, with specialemphasis on molecules in gas phase and in solutions.The first part of the thesisconcerns the two-photon absorption (TPA) process in the opticalwavelength region.
