Research Interests
During the first couple of years in Vienna I was mostly focusing on the surface science of TiO2 anatase and rutile.
In 2015 the group has purchased a combined STM/AFM machine in the q-Plus configuration (funded by the FWF Wittgenstein Preis Z-250 of Ulrike Diebold). This technique has proven very successful in various fields. The main focus of my research is exploring the possibilities offered by this technique on oxide surfaces and other wide-band-gap materials. The research has several directions:
* TiO2 anatase and rutile - these are well-understood oxides and serve as a suitable substrate for testing the capabilities and limitations of the q-Plus technique.
* Cubic perovskites KTaO3 (001) and SrTiO3 (001) - The surface science of ternary oxides is relatively poorly understood compared to binary oxides. We have developed a procedure for preparing nice (1×1) bulk-terminated surfaces of these materials. Such surfaces offer an interesting playground for investigating the material stability, surface chemistry, electronic structure, incipient ferroelectricity, etc.
* Scintillating materials (Eu-doped alkali halides)
My little research subgroup typically consists of 2-3 students working on my topics, and I closely collaborate with several doctoral students and postdocs from the Surface Physics group, focusing on materials like Fe3O4, Fe2O3, In2O3 and Ca3Ru2O7.
