Abstract
The paper presents the growth and optimization of carbon nanotube (CNT) and CNT/zinc oxide nanostructures to produce novel electron sources. The emitters studied in this project are based on regular array of vertically aligned 5 μm height and 50 nm diameter CNTs with a pitch of 10 μm. Such a cathode design allows to minimize electric field shielding effects and thus help in optimizing the emitted current density.
