Polymer electrolyte gated FET structure and room temperature device characteristics. (a) A schematic illustration of the four-probe device structure complete with the ionic polymer electrolyte layer (Bottom) with the molecular structure shown (Top). The molecular structure of pBTTT-C14 is also shown (Middle). (b and c) Typical current vs. Vg (b) and conductivity vs. Vg (c) data measured for a device in ambient air at room temperature and Vsd = −1 V. The Vg sweep rate was ≈60 mV/s.
