A dual cross-linked aromatic polythiourea gate dielectric with multifunctional capabilities for organic field-effect transistors

Abstract

A multifunctional gate dielectric material based on dual cross-linked aromatic polythiourea (c-PTU) networks for organic field-effect transistors is presented. Tailoring the dual covalent and noncovalent cross-links in the c-PTU gate dielectric enables all the advantageous capabilities of excellent insulating properties, including high capacitance, good solvent resistance and thermal stability, as well as low-temperature solution processing and photo-patterning.
