Roland studies the Fe3O4(001) surface and the adsorption and reactivity of metals on this surface. Fe3O4(001) has the unique property to stabilize isolated single metal adatoms up to ≈700 K [1]. Thus, it is an ideal model system to study the properties of metal adatoms and their interaction with each other and with molecules. The aim of Roland`s work is to gain insights into elementary processes in technologically relevant fields such as growth on oxides and heterogeneous catalysis in the ultimate limit of single atoms as active sites. These studies are performed using various surface science techniques in ultrahigh vacuum systems, primarily scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy (XPS), and low energy electron diffraction (LEED).
