I have always applied x-ray spectroscopic techniques to investigate electronic structure. Materials have ranged from organic semiconductors, wide-bandgap nitrides, wide-bandgap/metallic oxides, doped magnetic semiconductors, transition metal oxides, highly correlated electron systems with metal-insulator transitions and/or superconductivity, capped magnetic atomic nanowires as well as atomic ionised species in my early career. I have employed x-ray spectroscopic tools to probe or measure site-specific, symmetry-, state- and polarisation-dependent electronic structure of e.g. transition metal oxides and chemical bonds between ligand and oxygen in these oxides. These tools have also been applied to electronic structure of organic molecular semiconductors, phthalocyanine and porphyrin families and smaller molecules, either as thin films or as monolayers. Whether atoms, molecules, or bandstructures of extended solids, the simulation of the electronic structure of these materials is also my interest. e.g VB DOS/VBXPS, XES/RIXS, and XAS/NEXAFS simulated via density-functional theory (DFT) methods employing e.g. Wien2K (oxides) and StoBe codes (molecules), or Cowan code (atoms) [in my early career]; as well as (Cowan-derived) atomic-multiplet methods for resonant inelastic x-ray scattering (RIXS) and XAS/XPS at metal 2p core levels. Experiment and theory when well combined gives the best insight. Relatively recent investigations studied self-assembled one-dimensional atomic-width cobalt nanowires on vicinal surfaces; specifically their changed magnetic behaviour upon gold capping, studied by STM, XPS, LEED, RAS-MOKE and XMCD. This renewed surface science focus progressed to organics and one-dimensional organic nanostructures. Thus, the last 4 years have involved on-surface synthesis of both 2-dimensional molecular networks and 1-dimensional nanostructures, built from small halogenated precursor molecules, such as the prototypical di-bromo-bi-anthracene (DBBA), where surface heating induces coupling and 7-carbon atom wide graphene-nanoribbons (7-AGNR). Novel precursors and the joint use of halogenated porphyrin precursors gives opportunities for interesting on-surface strategies involving heterostructures. The study of porphyrin ribbons and heterostructures and their interactions with volatile organic compounds is a key objective.
