I am interested in the application of x-ray spectroscopic techniques to the investigation of the electronic structure of materials. Materials studied range from organic semiconductors, wide bandgap nitride semiconductors, wide band gap oxide semiconductors, doped magnetic semiconductors, transition metal oxides and highly correlated electron systems exhibiting metal-insulator transitions and superconductivity as well as capped magnetic atomic nanowires.
More specifically my current research has a number of distinct strands. The first and second strands of research are the measuring of site-specific, symmetry-, state- and polarisation-dependent electronic structure of transition metal oxides, specifically the study of chemical bonding in rutile type transition metal oxides. and secondly the investigation of electronic structure in organic molecular semiconductors such as the phthalocyanine family of compounds.
For both of these strands I am also interested in the simulation of the electronic structure of these materials and the RXES and XAS via density-functional theory (DFT) methods employing Wien2K and StoBe codes; as well as atomic-multiplet methods for resonant inelastic x-ray scattering (RIXS);
The third strand of my research concerns the magnetic behaviour of low-dimensional atomic nanowires; the growth of low-dimensional several-atom-width nanowires on stepped vivinal single crystal metal surfaces and their characterisation by x-ray magnetic circular dichroism (XMCD), element-specific hysteresis loops and magneto-optic spectroscopies.
An earlier strand was the investigation of electronic structure of doped magnetic semiconductor materials.
These investigations all use high-brightness synchrotron x-ray sources such as MAX-lab (Swedish National Synchrotron facility), the NSLS (National Synchrotron Light Source, New York), the ALS (Advanced Light Source, California) and the SLS (Swiss Light Source) and ELettra (Italy). The techniques used are soft x-ray absorption spectroscopy (XAS), soft x-ray emission spectroscopy (XES), soft x-ray photoemission spectroscopy (XPS) and x-ray magnetic circular dichroism (XMCD). These techniques reveal detailed information about the conduction band structure, the valence band structure and the core-level structure of the material respectively. Further, through the use of resonant soft x-ray emission (RXES) the low-energy electronic excitations in a material can be directly probed leading to a resonant inelastic x-ray scattering (RIXS) spectrum, or chemical site dependent XES spectra can be obtained, particularly in the case of organic compounds.
