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

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 V s for common polymer and other semiconductor families at V ≤ 2 V owing to high areal capacitance (>4 µF cm ) from combined polarization of CF interface dipoles and electrical-double-layer formation.
