Georgia Tech-COPE Distinguished Lecture Series - Michael Chabinyc

Moving Charge in Semiconducting Polymers  

Organic semiconductors provide the opportunity for low-cost fabrication of novel flexible thin film electronics. There has been significant progress in organic light emitting diodes (commercial products), solar cells (efficiencies of 10%), and thin film transistors (carrier mobilities > 1 cm2/Vs).  Despite these successes important questions remain unanswered about the connection between microstructure and optoelectronic properties. Our ability to determine charge transport pathways in organic materials has benefitted from soft x-ray scattering and high resolution transmission electron microscopy. In both cases, long-range correlation of conjugated backbones in high carrier mobility polymers is observed providing a clear connection between morphology and charge transport. We have also discovered the existence of quadrites in donor-acceptor polymers suggesting a strategy for future materials design.  These advances suggest future avenues for new applications for organic semiconductors. The prospects of organic materials for application as thermoelectric materials will be discussed and recent work on electrical doping will be presented.
