“Functionalities from Corrugated Sp2-Bonded Monolayers”

Single layers of hexagonal boron nitride (h-BN) or graphene exhibit strong corrugations with periodicities in the few nanometer range when grown on transition metal surfaces with a large lattice mismatch. The geometrical corrugation is accompanied by a corrugation of the electrostatic potential, which provides these surfaces with interesting functionalities, e.g. for the trapping of molecules. The corrugation can be lifted by the intercalation of hydrogen atoms underneath the monolayer, leading to effects observable also on the macroscopic scale. In my presentation I will give an overview on recent results on these nanomaterials obtained both, in ultra-high vacuum and in electrochemical environment.
