21. Electronic structure studies using resonant X-ray and photoemission spectroscopy
Sammanfattning : 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.

22. Electronic Structure Calculations: Materials with Weak and Strong Correlations
Sammanfattning : This thesis is devoted to studies of various electronic properties which can be extracted from photoemission spectroscopy. Both weakly and strongly correlated systems are discussed, ranging from free electron metal surfaces to strongly correlated copper oxide compounds. LÄS MER
23. Synchrotron radiation study of free and adsorbed organic molecules
Sammanfattning : In this licentiate thesis, organic molecules, namely Cobalt Phthalocyanine (CoPc) and Biphenylene, have been studied by means of synchrotron radiation-based spectroscopic methods (Photoemission Spectroscopy (PES) and X-ray Absorption Spectroscopy (XAS) in combination with Density Functional Theory (DFT) calculations.Paper I is a combined experimental and theoretical investigation of electronic structure of CoPc.

24. Photoemission Electron Microscopy for Ultrafast Nano-Optics - Femtoseconds to Attoseconds
Sammanfattning : Ultrafast nano-optics is a new and quickly evolving research field centred around the control, manipulation, and application of light on a nanometre and femtosecond scale. This can lead to improved electro-optical devices, more sensitive spectroscopy, and real-time control of chemical reactions. LÄS MER
