Abstract
We report fabrication of aligned array carbon nanotube (CNT) electrodes for organic electronic device applications. The ultra-high density aligned CNT array was assembled via dielectrophoresis (DEP) from a high quality surfactant free and stable aqueous CNT solution. The CNT source and drain electrodes were formed though oxidative cutting of aligned CNT array by electron beam lithography and precise oxygen plasma etching. As an example of usefulness of this electrode, organic field effect transistor was fabricated using a thin film of poly (3-hexylthiophene) and the electrical transport properties of the devices were studied. Compared to the control devices fabricated with gold electrode, devices based on CNT array electrode show better performance with higher mobility, higher current on/off ratio and higher reproducibility. This study demonstrates that aligned array CNT electrode will have potential applications in fabricating organic electronic devices.
