Novel carbon nanotube based three terminal devices

Abstract

Carbon nanotubes since their discovery have created much industrial and scientific interest. Their unique properties in electrical conduction, chemical robustness and the ability to control the growth of aligned CNT films makes them an ideal candidate for high intensity electron sources. Combining these properties with that ability to solubilise CNTs within an aqueous solution further extends the application fields associated with these unique materials. In this work we made use of an acid oxidised carbon nanotube ink that has been developed by Ago et al. (1999) to provide a simple route for controlling threshold fields and the current density in a three terminal device configuration.
