  1. s s s s s s s s s s The key to making high mobility polymer thin film transistors: nucleation of crystals off of the gate dielectricStanford MRSEC, DMR-0213618 • When conjugated polymer crystals nucleate off of the gate dielectric, the conjugated backbones, shown in red, are all aligned. Charge can easily hop from one grain to another. • Proven strategies for nucleating crystals on the dielectric • Make the dielectric smooth • Coat the dielectric with OTS • Use high boiling point solvent or anneal the film • Use high molecular weight polymers.
