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<sup>2</sup> V<sup>-1</sup> s<sup>-1</sup> for common polymer and other semiconductor families at V<sub>G</sub> ≤ 2 V owing to high areal capacitance (>4 µF cm<sup>-2</sup> ) from combined polarization of CF interface dipoles and electrical-double-layer formation.
