SummaryTechnical and industrial relevant chemical processes such as catalysis and electrochemistry occur at solid surfaces in complex environments in terms of material composition, pressure, temperature and medium. As a consequence, the atomic scale structure and the environmental composition close to the active material which governs the chemical processes are notoriously difficult to determine.T

Summary Ambient pressure cell at SPECIES Electron spectroscopy has provided much of our current knowledge on the chemical and physical processes involved in the complex interactions between a solid surface and its surroundings. Such processes are for example important for surface catalysis, corrosion and thin film growth.As the surface state depends strongly on its environment, it is vital that su

Summary The interactions of electrons in materials are a rich and complex source of physical problems, in part due to the issues brought about by dealing with the large number of electronic many-body interactions, both with other electrons and with the parent ions.  These interactions give rise to fundamentally quantum mechanical states such as superconductivity and magnetism.  New quantum states

SummaryWe develop and use methods for analysis of nanostructures with highest possible spatial and temporal resolution. One aim of this research is to understand the role of the surfaces and interfaces for their function and properties. Another goal is to study devices under as realistic conditions as possible. The aim is both fundamental physical understanding as well as enabling the design of no

SummaryAccelerator physics deals with how particle beams are created, accelerated, steered, measured and controlled to finally be tailored to specific purposes. This is relevant for laboratories such as ESS, CERN and the MAX IV, but also for medicine or semi-conductor development.The focus of the Accelerator Physics group is on electron accelerators to produce synchrotron radiation. While our main

Photoionization dynamics Illustration of an electron wave-packet emitted when attosecond pulses (blue) impinge an atom, schematized by a potential well. Attosecond pulses created by high harmonic generation (HHG) in gases allow us to study fundamental light-matter interaction processes with novel experimental techniques. The ultrashort light pulse leads to the creation of a wave packet that can be

Cluster dynamics - a step towards complexity Illustration of water molecules (red) with ammonia molecules (blue-grey) in a nano-droplet. Photoinduced processes in complex systems can be modeled as a sequence of events initiated by the absorption of a photon. Photoionization of an atomic electron is followed by electronic relaxation which results in a migration of charge within the atom. The need t

An FeO model catalyst on Ag(100) by STM (left) and LEED (Right) - taken from ref 1. It is next to impossible to perform operando experiments without prior detailed atom scale information on the model catalyst, due to the complexity of the gas-surface interaction and the data interpretation. We will therefore apply our standard UHV surface science techniques available to us such as Scanning Tunnell
