Conducting Polymer Transistors Making Use of Activated Carbon Gate Electrodes
The characteristics of the gate electrode
have significant effects on the behavior of organic electrochemical
transistors (OECTs), which are intensively investigated for applications
in the booming field of organic bioelectronics. In this work, high
specific surface area activated carbon (AC) was used as gate electrode
material in OECTs based on the conducting polymer poly(3,4-ethylenedioxythiophene)
(PEDOT) doped with poly(styrenesulfonate) (PSS). We found that the
high specific capacitance of the AC gate electrodes leads to high
drain-source current modulation in OECTs, while their intrinsic quasi-reference
characteristics make unnecessary the presence of an additional reference
electrode to monitor the OECT channel potential
