Organic electronics on flexible substrates-paper or plastic?
ABSTRACT In this paper, we have developed a robust, reliable organic TFT process that allows the fabrication of organic TFTs and integrated circuits on a variety of substrates, including polyethylene naphthalate (PEN), polyethylene terephthalate (PET), and paper. Although the static and dynamic TFT performance depends somewhat on the properties of the substrate material, we were able to demonstrate functioning ring oscillators on all three types of substrates (PEN,PET, and paper), with signal propagation delay as low as 22 μsec per stage.
Conference Paper: Biocellulose based materials for organic field effect transistors.[Show abstract] [Hide abstract]
ABSTRACT: Biocellulose and biocellulose composites are being investigated as substrates and as gate dielectrics for organic field effect transistors. Spin coated films of regioregular poly(3-hexylthiophene) (RR-P3HT) and thermally evaporated pentacene were used as semiconducting materials. Preliminary results on device characteristics are reported.Proceedings of EUROCON 2011, International Conference on Computer as a Tool, 27-29 April 2011, Lisbon, Portugal; 01/2011
