Organic and carbon-based electronics printed onto flexible substrates

In this paper, examples of organic and carbon-based thin-film transistors (TFT) that have been fabricated onto plastic substrates. The fabrication of these devices was achieved using the transfer printing method. With this method, each of the components (Au electrodes, polymer dielectric layer and semiconductor layer) were printed onto a plastic substrate using only pressure and temperature. This constitutes a very simple fabrication process that relies primarily on differential adhesion and eliminates all chemical processing on the device substrate.
