My experimental work is dedicated to the exploration of surface-supported self-assembled nanostructures. I expend considerable efforts to improve the control over the self-assembled growth beyond the state-of-the-art. Advanced materials, including metal nanostructures and molecular architectonic on metal surfaces, are engineered, almost atom-by-atom, molecule-by-molecule, to achieve superior properties for various applications.
I am exploring new concepts for magnetic data storage, which go beyond current thin film technologies. To this end, I am studying the magnetic anisotropy energy (MAE) at the sub-nanometer scale. This will contribute to an improved atomic-scale understanding of the MAE, which can greatly facilitate the engineering of advanced magnetic materials for extremely high-density magnetic recording. The work will also demonstrate self-assembled patterned media based on magnetic nanoclusters which, if applied in magnetic recording, would allow for unprecedented bit densities beyond several Terabit per square inch. Exploring the limit of magnetic storage density at room temperature is a key objective here.
In collaboration with my partners, I am also developing highly organized surface-supported metal-molecule frameworks systems, with potential for application in magnetism, catalysis or gas storage. The self-assembly of organic molecule ligands to nano-architectures is a very attractive strategy, both for its efficiency as well as for the high structural quality that can be achieved. The results will also be stimulating for related efforts in supramolecular engineering on solid surfaces which may lead to devices for molecular electronics, sensors, catalysts, magnetic data storage, bioengineering techniques, actuators on surfaces, photoswitchable systems and many more.
