Summary on Grant Application Form
Very recent work in the Cavendish group has demonstrated the potential for realistic transistor circuits to be made by direct printing from solution, of polymer semiconductors, metals and insulators. This has been enabled by the following breakthroughs: - Demonstration of conjugated polymer thin-film transistor devices with mobilities of 0.1 cm2/Vs.- Development of new high-mobility polymer semiconductors with good environmental stability- Development of high-resolution ink-jet printing using surface free energy patterning of the substrates that has enabled direct printing of all-polymer transistor devices with channel lengths of 5 micrometers.The opportunity is now ripe to push both science and circuit/device engineering to meet performance requirements for practical applications of printed electronic circuits, such as active matrix displays or cheap, disposable logic circuits. We are requesting funding for a state-of-the-art semiconductor printing laboratory , which will provide us with the infrastructure that is required to take our research from the individual device to the integrated circuit level and keep our position as one of the leading groups in this rapidly moving field. The project is a focussed, interdisciplinary programme aiming (a) to develop a viable technology for manufacturing integrated polymer transistor circuits by direct ink-jet printing and (b) to develop printing techniques for submicrometer transistor devices in order to explore new pathways for the solution self-assembly of molecular electronic devices.
