- Charge transport in semiconducting polymers suffers from disorder and this remains a challenge in processing today. A novel, low-cost technique that controls nanoscale morphology in polymer films was developed. Highly ordered polymer films were achieved and employed in field effect transistors and light emitting transistors (LETs). A 10-fold enhancement in charge carrier mobility and the highest reported current density and luminance in LETs was achieved. This significant advancement in LETs with potential to allow injection lasing in polymers initiated a new challenging project on the topic led by the group of Noble Laureate Prof Alan Heeger at Santa Barbara (ajhe@physics.ucsb.edu).
