The Scientific Facility "Interface Analysis" (Grenzflächen Analytik, GA) (headed by provides service (and facilities) to quantify the chemical composition and to determine the electronic structure and the atomic geometry of solid-solid and gas-solid interfaces.
Research in the Interface Analysis group is directed towards the atomic and electronic structure of surfaces and thin films of technologically interesting materials like graphene and transition metal dichalcogenides (TMDs). The goal of these research activities is a fundamental understanding of growth, interface and crystal formation and elecronic structure at the atomic scale. A major research project at present is the growth and manipulation of electronic properties of epitaxial graphene on SiC.
