Doping is commonly used to improve performance in semiconducting devices but has not previously been successful for electron transporting or n-type, organic electronic materials. Now, an approach developed by KAUST uses a dopant, an additive that boosts the electronic performance and water stability of an n-type semiconducting polymer, to produce the first water-stable n-doped, organic electrochemical transistors, known as OECTs.
