Abstract

Organic transistors will be one of the basic components of future plastic electronic devices as they are a precondition for the manufacture of low-cost, integrated plastic circuits (IPCs). Thus investigations on all-polymer electronics devices, i.e. electronics without any silicon and metal constituents, are of growing interest. We report here our recent results on the fabrication of all-polymer organic field-effect transistors (OFETs) comprising conductive poly(ethylenedioxythiophene)-poly(styrene sulfonic acid) PEDOT/PSS systems as electrode material, regioregular poly(3-hexylthiophene) as semiconductor, as well as polymer substrates and dielectrics. All devices were manufactured under ambient conditions by means of spin-coating and standard lithographic techniques. OFET characteristics and simple shelf lifetime tests are reported and reveal an unexpected high device stability.
