Welcome to the Nano-optoelectronic Materials and Interface group!

Our group is affiliated with the Molecular Spectroscopy Department at the Max Planck Institute for Polymer Research.

Our research focuses on optical and electrical characterization of low dimensional optoelectronic materials and their integration into devices. The material systems which we are interested, include but are not limited to: two dimensional (2D) monolayer semimetals (e.g. graphene) and semiconductors, quasi-2D semiconducting colloidal nanoplatests and 1D atomically precise graphene nanoribbons, etc. Employing time-resolved, ultrafast spectroscopies (THz spectroscopy, transient absorption, time resolved photoluminescence spectroscopy etc.), we aim to understand fundamental processes of photogenerated carriers in optoelectronic materials, e.g. carrier generation, hot carrier cooling, exciton formation, charge separation and charge transport at nanoscale. Eventually, we wish to correlate these ultrafast dynamics with the performance of optoelectronics (laser, LEDs), and energy conversion efficiency in the photovoltaic and photochemical cells.
