This Ph.D. position is to use techniques such as neutron reflectometry, x-ray diffraction, spectroscopy ellipsometry and AFM to probe the way the conformation and dynamics of polymer molecules are altered by their proximity to surfaces and interfaces in thin films of the kind that are used in semiconducting polymer devices, exploring in more detail, for example, recent evidence from our group that an interface can stabilize a second amorphous phase in the polymer PCDTBT causing anomalies in the glass transition temperature of the film. Film formation processes will also be considered through the use of in situ light scattering during spin coating. Through collaboration with D Lidzey’s group we will study how these effects influence device performance.

The successful candidate for this position will hold a good relevant undergraduate (first, upper second or equivalent) or Masters degree (Physics, Materials Science, or Chemistry are certainly acceptable).

Funding Notes:

UK Nationals only. European nationals who have been living in the UK for an extended period may also be considered.

The position is funded for 3.5 years and includes a stipend of £13726.
