S01 - High-harmonic spectroscopy of molecular films

Project description

In project S01, we will perform high-harmonic spectroscopy on organic molecular crystals. Molecular crystals bridge the gap between individual molecules with well separated states and bulk crystals with a band structure. This is because organic crystals feature electronic couplings of intermediate strength between the molecules.  We will address the questions how the electronic and geometric structure of the molecular crystals affect the harmonic emission and which polarization properties result for the emitted harmonics.
