We have been studying various Dirac materials including topological insulators based on atom-surface scattering: A sensitive method to determine the electron-phonon coupling[1,2], while lineshape broadening upon inelastic scattering allows to follow the nanoscale-nanosecond motion of water at Dirac materials[3,4].
Furthermore, we will discuss the growth of hexagonal boron nitride (hBN) based on real-time investigations of the structures during chemical vapour deposition. We illustrate that a precursor structure precedes the growth at lower temperatures and an additional phase co-exists with h-BN at higher temperatures - thus shining light on a largely unexplored area considering the growth of 2D materials.
