Carbon nanotubes have been attracting attention because of their unique physical properties and their application potential for field emission cathode. Carbon nanotubes possess the following properties favorable for field emission material
such as a high aspect ratio and sharp tip
high chemical stability
high mechanical strength
stable at high temperature. Some research works on carbon nanotubes field emitter and field emission display have been reported. Here
a kind of carbon microtubes and its field emission properties are introduced. They have some different properties with carbon nanotubes
and the density is lower than carbon nanotubes bundles. These carbon microtubes are directly synthesized by liquidoid epitaxy method on silicon substrates at low temperature. The field emission properties of carbon microtubes are reported too. Carbon microtubes film is synthesized in liquid by electrolysis. The graphite plate is as anode
and n-silicon substrate with resistivity of 4-8 cm is as cathode. The electrolysis current is about 5-8mA/cm2
and applied voltage is 800-1500V. Temperatures of the methanol base solution is maintained at 60C in process of deposition of carbon microtubes. Carbon microtubes film is observed by scanning electron microscopy(SEM)
as shown in fig.1(a
b). The wall's thickness of carbon microtube is about 60nm. The diameter of carbon microtube is about 0.8 m. Raman spectrum of carbon microtubes film shows the two peaks at 1342and 1560cm-1. The field emission properties of carbon microtubes are measured in high vacuum chamber(10-5Pa). The emission area of carbon microtubes is 0.5cm 0.5cm. The threshold of field emission of the carbon microtubes film is about 3.6V/ m. Field emission property of carbon microtubes film is shown in fig.2. Another
when the electric field between anode and cathode is 10V/ m
the electric field distribution on single carbon microtube is also given after calculation according to electric field theory. Fig 3 shows that electric field distribution vertical section on the of single carbon microtube top with 2 m of highness. These results may help us to understand field emission properties of carbon microtubes. According to research results
it is found that liquidoid synthesis is simple method to produce carbon microtubes cold cathode material
and the carbon microtubes have better field emission properties. 2005 IEEE.

Multi-wall carbon nanotubes were deposited on the patterned silicon substrates using electrophoretic deposition. The surface images of carbon nanotubes on substrate were observed by scanning electron microscopy. Field emission properties have been tested with a diode structure in a vacuum chamber below 510-4 Pa. The emission area measured is 1.0mm 2. Emission current density up to 30mA/cm2 at an electric field of 8V/m has been obtained. Patterned deposition of carbon nanotubes by electrophoresis is a potential method to prepare field emission arrays. 2004 IEEE.
