D1.1 - Ultrafast exciton and charge dynamics in ordered organic semiconductor systems
Principle Investigator: Prof. Paul van Loosdrecht
The main goal of this project is to establish an understanding of the relation between exciton and charge generation and transport, and molecular arrangement. To address this, we use a variety of ultrafast spectroscopic techniques, including transient absorption spectroscopy, time resolved Raman spectroscopy, and 4-wave mixing transient grating experiments.
Understanding of this type or structure/property relation is essential for the further development of pi-conjugated material based functional devices.
