Toward Sustainability in Organic Electronics: A Performance Check for DNA Complexes as Dielectric Layer in P3HT based OFET

K. Shiju, T. Praveen, Jayan Manuvel, Rosemary Davis


Notwithstanding its manifold advantages the fast emerging area of organic electronics can invariably lead to the production of huge amounts of plastic waste and therefore developing ecofriendly organic electronic components to make it sustainable has become a priority task. Here an effort has been made in this direction where in a well-known bio material complex of deoxyribo nucleic acid and cetyltrimethylammonium chloride (DNA_CTMA) is applied as dielectric layer in a top-gate organic field effect transistor (OFET) with Poly 3-hexylthiophene (P3HT) as channel material. The DNA used was isolated from the leaf of Asteracea species plant by the biosynthesis mechanism. The device returned modest but promising operating parameters.
