This thesis covers a study of the photoexcited relaxation dynamics in superconducting ironbased pnictides, cuprates and charge-density wave systems by means of femtosecond laser spectroscopy. To examine the temperature and fluence dependence of photoinduced reflectivity transients ΔR/R in iron-based pnictides and cuprates, we apply a standard double pump-probe technique, while …
This thesis presents a study of different nanoscale functional properties of Mo6S9-XIx nanowires and demonstrates a straight-forward functionalization route based on self-assembly. In order to ascertain their basic functional properties, studies of dispersion and electromobility under different conditions were performed. It was found that the nanowire bundles, due to their …
