A fully integrated field emission diode (FED) using
carbon nanotubes as electron field emitter was
constructed. The device was designed and fabricated
on a glass substrate by screen-printing thick film
technique. The FED was operated at 100 V for giving
a forward current density of 180 mA/cm2. A leakage
current of 1 pA was measured then a 1000 V reverse
voltage was applied, indicating that a high voltage
blocking capability was obtained from such a device.
From theoretical calculation and experimental
results, the FED can be operated in megahertz due to
very high speed of electrons traveling through them
vacuum gap on forward operation and a small residue
capacitance as well as minimum the reverse recovery
time on reverse operation. The high performance of
the novel FED was fabricated by a cost effective
process combined with nanomaterials which opens up a
route to produce miniaturized vacuum devices and new
applications for such kind of the integrated vacuum
microelectronic device.
