Exciton dynamics in organic semiconductors

Full-time Project: yes

Project Description:

This project aims to measure the (slow) dynamics of excitons in organic semiconductors. It will use atom specific probes of exciton wavefunction, as a function of time, which allows the evolution of the  exciton to be sampled within the molecule over time. The primary technique will be laser pump  / muon spin resonance probe spectroscopy (photomusr), backed up with optical spectroscopy  and DFT calculations of the excited state and molecular structure. Molecules  will be commercial or  made via collaboration. This  work may be extended to studying donor-acceptor state dynamics in organic photovoltaic cells.

Requirements:

A good undergraduate degree in physics or related discipline.
