Description :
In this talk, some of the most promising uses of conducting polymers (CP) will be discussed, aided by specific experimental examples to motivate the modeling strategy with a focus on poly(3-hexylthiophène) (P3HT). A methodology for growing well-aligned crystals from the melt phase in simple polymers such as Polyethylene (PE) will be discussed and how this may be extended to a P3HT model. The computational methodology used to model thermal and electronic transport in CPs will be discussed and associated bottlenecks highlighted. This will touch on classical/ab initio methods such as density functional theory and classical (Marcus) charge transport models.
