제목 High-performance, Flexible Graphene Field Effect Transistors with Ion Gel Gate Dielectrics
초록 A high performance low-voltage graphene field-effect transistor (FET) array was fabricated on a flexible polymer substrate using solution-processable, high-capacitance ion gel gate dielectrics. The high capacitance of the ion gel, which originated from the formation of an electric double layer under the application of a gate voltage, yielded a high on-current and low voltage operation below 3 V. The graphene FETs fabricated on the plastic substrates showed a hole and electron mobility of 203±57 and 91±50 cm2/Vs, respectively, at a drain bias of -1V. Moreover, ion gel-gated graphene FETs on the plastic substrates exhibited remarkably good mechanical flexibility. This method represents asignificant step in the application of graphene to flexible and stretchable electronics.
