Ultrahigh Mobility in Solution-Processed Solid-State Electrolyte-Gated Transistors

Abstract

A new concept of a high-capacitance polymeric dielectric based on high-k polymer and ion gel blends is reported. This solid-state electrolyte gate insulator enables remarkable field-effect mobilities exceeding 10 cm(2) V-1 s(-1) for common polymer and other semiconductor families at V-G <= 2 V owing to high areal capacitance (>4 mu F cm(-2)) from combined polarization of -C-F interface dipoles and electrical-double-layer formation.
