Ultrafast Spectroscopy - Elucidating Quantum Dynamics

The motion and dynamics of charges, excitons and phonons control the properties of semiconductor materials and devices. 

Using various ultrafast spectroscopy techniques with time resolution down to 10fs we study exciton, charge and phonon dynamics in these systems with unprecedented sensitivity. This has allowed us to unravel a host of interesting physical phenomena, such as ballistic charge propagation in molecular systems, the quantum mechanics of singlet exciton fission and exciton-phonon coupling in semiconductors.
