Faculty Profile of Ulrich Starke

In our group we study the atomic and electronic structure of solid surfaces and 2D materials. A strong focus of the research is the growth and functionalization of epitaxial graphene on Silicon Carbide. By means of atomic intercalation we can tailor graphene’s electronic properties. We use angle-resolved photoemission spectroscopy (ARPES) to investigate doping and renormalization of the π-bands in graphene – in the home lab and at synchrotron facilities. Structured SiC substrates are the basis to grow epitaxial graphene nanoribbons with a one-dimensional electronic spectrum. The interaction of hetero-epitaxial 2D materials (e.g. transition metal dichalcogenides) and molecular layers with the graphene and its influence on both, the graphene and the 2D layer is studied with a multitude of surface science methods in ultra-high vacuum.
