Abstract :
A polyanionic proton conductor, named poly(4-styrenesulfonic acid) (PSSH), was used to gate an Organic Thin-Film Transistor (OFET) based on p-type poly(2,5-bis(3-tetradecylthiophen-2-yl)thienol [3,2-b]thiophene) (pBTTT-C14) organic semiconductor. Upon applying a negative gate bias, a large electric double layer capacitors (EDLCs) are formed at the gate-PSSH and at the pBTTT-PSSH interfaces due to the proton migration in the polyelectrolyte. Different device configurations are evaluated and their electrical performance along with their implementation on flexible Kapton substrates is discussed.
