1. Conjugated Polyelectrolytes for Optoelectronic ApplicationsGuillermo C. Bazan, University of California-Santa Barbara, DMR 1005546 Organic light emitting field effect transistors (OLEFETs) are hybrid devices with the potential to be incorporated into a wide range of displays, for example smartphones. OLEFETs provide the means to control light output intensity by means of a gate potential, essentially combining the operation of transistors with light emitting diodes. NSF DMR research has shown that thin conjugated polyelectrolyte layers can improve efficiency of electron injection and therefore light emission.1 Moreover, the device fabrication is extremely simple and relies on solution deposition methods.
