The surface of a material is critical for its properties, especially in heterogeneous catalysis. Surfaces properties can be probed, for example, by H atom scattering. However ab-inito theoretical investigations of H atom ...

Piezo force microscopy has been used to visualize nanoscaled surface charge density waves in a modulated ferroelectric system for the first time. Those self-organized structures are found in incommensurate systems close ...

This work investigates the surface dynamics of vanadium dioxide with nitric oxide in dependence of its metal-to-insulator transition (MIT) at 68 °C. At lower temperatures VO2 has a monoclinic lattice structure which has ...

In this work sodium doped water clusters are studied by means of photoionization reflectron time-of-flight mass spectrometry. Addition of an laser pulse of infrared radiation to the photoionization laser pulse sequence ...

This thesis contains experimental and theoretical fundamental studies of energy transfer processes on various surfaces via inelastic hydrogen atom scattering using the Rydberg atom tagging machine. The initial investigations ...

Part I of this work introduces a technique for the generation of H-atom pulses with unprecedented time resolution. In part II an extensive study of the associative desorption reaction of hydrogen isotopologues from metal ...

One of the goals of studying molecule-surface interactions is to understand the details of the chemical reactivity at surfaces. The exchange of energy between a gas and a solid is a complex sequence of events even when ...

I have constructed a full-dimensional potential energy surface (PES) for a H atom interacting with a Au(111) surface by fitting the analytic form of the Effective Medium Theory to density functional theory (DFT) energies. ...

In the first part, the photodissociation dynamics of methyl azide are probed by photofragment translational spectroscopy at 248 nm and 193 nm dissociation wavelengths under collision-free conditions. At 248 nm, the only ...
