Ultrafast processes in molecules investigated by femtosecond time-resolved spectroscopy Within the last two decades ultrafast laser spectroscopy has led to fundamentally new insights of dynamical processes in atoms, molecules, clusters and condensed matter. In this talk I will introduce femtosecond time-resolved spectroscopic methods with a focus on the investigatio ... more |

Megahertz Organic Thin-Film Transistors for Flexible Displays Organic thin-film transistors (TFTs) can typically be fabricated at temperatures below about 100 °C and thus not only on glass or quartz substrates, like hydrogenated amorphous silicon (a-Si:H) or polycrystalline silicon TFTs, but also on a variety of unconventional substrates, ... more |

Solution processed organic field-effect transistors for large area and low cost applications Organic-based devices are currently attracting great attention for applications where low-cost, large area coverage and flexibility are required. The best performing electronic devices to date are those comprising single crystals of organic semiconductors, although they are neith ... more |

Probing ultrafast electron dynamics in momentum, space, and time Optically excited (hot) electrons play a crucial role for many fundamental chemical and physical phenomena occurring at surfaces, interfaces, and in bulk materials. They, for instance, determine the properties of photo-induced catalysis at surfaces, and the efficiency of charge a ... more |

Understanding the interplay of electronic and geometric structure at inorganic/organic interfaces It is often stated that „geometry determines function“, i.e. that the specific atomistic arrangement of a system sensitively determines its electronic properties. In the present talk, we will use density functional theory calculations – corroborated by a diverse set of expe ... more |

Intermolecular Interactions: Surfaces, Molecules and Molecular Solids In the last century, the nature of strong interactions between atoms, which are responsible for configuration and conformation of molecules, were in the focus of research. In modern quantum chemistry, such strong interactions are nowadays well understood. However, in recent years ... more |

Nano-Quantum-Optics: From single photons and emitters to cooperative effects I plan to start this presentation with an overview of our work over the past decade on the efficient coupling of light and single quantum emitters, leading to the single-photon communication of two individual molecules at long distances [1]. In this context, we will also discuss ... more |

The Formation of Terrestrial Planets and the Race to Find a Second Earth Almost every day we can find news like the following one, from February 22nd this year, in the New York Times:
"Not just one, but seven earth-size planets that could potentially harbor life have been identified orbiting a tiny star not too far away, offering the first realist ... more |

New applications for molecular framework materials: hydrogen isotope separation and long-range ordering Molecular framework materials such as MOFs and COFs are known for their large surface area and resulting high affinity to adsorb and to separate molecules. Selective adsorption is possibly by geometric control (pore size) and specific interactions. It is less known that those int ... more |

Designable clustering and precipitation kinetics in aluminium alloys Although Al-Mg-Si alloys are the most frequently used group of precipitation hardened aluminum alloys, early stages of aging are still far from being fully understood. The adverse effect of natural aging on the artificial aging, which increases the necessary duration of the heat ... more |
