Synopsis

In this thesis the optical properties of quasi two-dimensional organic molecular crystals are investigated. Within this class of materials some systems are metallic, some are insulating due to charge-order, and others even become superconducting. The driving force behind the ground states is the different degree of effective electronic correlations. Recent experimental and theoretical studies of strongly correlated materials suggest that fluctuations of the ordered state may mediate superconductivity. The intention of this work is to prove the presence of such charge fluctuations and reveal their relation to superconductivity. To do this, we investigated BEDT-TTF based organic conductors by optical spectroscopy covering a broad frequency (8-20000 cm−1 ) and temperature (1.8-300 K) range using FTIR- and THz-spectrometers. In addition, the transport properties are investigated by dc four-point contact measurements and microwave cavity perturbation technique.

About the Author

Stefan received his diploma from the RWTH Aachen. As a PhD student he joined Martin Dressel's group at the Universität Stuttgart. The present text summarizes parts of his work there. Now he is with Andrea Cavalleri at CFEL in Hamburg in order to investigate the ultrafast dynamics and control of phase transitions in complex correlated materials.
