Field‐Effect Transistors with Mixed Ionic‐Electronic Gate

Abstract

Field-effect transistors with mixed ionic-electronic conductors have been prepared by varying the ratio of room temperature ionic liquid and emeraldine salt of polyaniline. Transistor with sufficiently high electronic conductivity (32 mol% ES-PANI) and Au gate contact exhibited theoretical behavior of insulated gate field-effect transistor. On the other hand the purely ionic gate behaved irreproducibly, indicating that a capacitive divider has been formed in the gate.
