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 cm2 V-1 s-1 for common polymer and other semiconductor families at VG ≤ 2 V owing to high areal capacitance (>4 µF cm-2 ) from combined polarization of CF interface dipoles and electrical-double-layer formation.
