A high transconductance accumulation mode electrochemical transistor

Adv Mater. 2014 Nov 26;26(44):7450-5. doi: 10.1002/adma.201403150. Epub 2014 Oct 13.


An organic electrochemical transistor operates in accumulation mode with high transconductance. The channel comprises a thiophene-based conjugated polyelectrolyte, which is p-type doped by anions injected from a liquid electrolyte upon the application of a gate voltage. The use of ethylene glycol as a co-solvent dramatically improves the transconductance and the temporal response of the transistors.

Keywords: accumulation; conjugated polyelectrolytes; electrochemical; transconductance; transistors.
