In the DuVel Labs, we are interested in complex molecular systems, especially solid surfaces, films, and various nanostructures. A focus is on synergy of dynamics, composition, and topography. The ultrafast dynamics is revealing electronic-vibrational-rotational states of molecules in real time, based on femtosecond laser spectroscopy in UV-VIS-IR-THz ranges. The chemical composition is based on secondary ion mass spectrometry with up to ppb sensitivity on elements and molecular fragments. Three dimensional chemical composition, by means of depth profile, is correlated with the topography which is based on scanning probe microscopy with sub-nanometer spatial resolution. Such a versatile synergy can shed some light not only on fundamental issues, but also on applications.
