The field emission properties of single-wall carbon nanotubes with purity higher than 70%,which were produced by dc arc discharge evaporation of a carbon electrode including 1% Fe catalyst in H2-Ar mixture gas was studied.The single-wall carbon nanotubes that were produced by this method possess high a ‘clean’ surface since the coexisting Fe catalyst nanoparticles can be completely eliminated by a two-step purification process.The field emission properties was verified by measuring the emission current density(J) versus the applied electric field(E), the corresponding Fowler-Nordheim(F-N) plot for the sample.Through looking at the emission photos, the uniformity of field emission is found to be excellent.

The effects of various metal intercalations ( Li , Na and Be ) on the electronic structures and the field emission properties of single-wall carbon nanotubes (SWNT) were investigated using the periodic plane-wave DFT method. We found that intercalations of metal tend to shift the conductive characteristics of the SWNT from those of a semiconductor to those of a quasi-metallic conductor. The Fermi levels for all metal-intercalated in SWNT are moved toward the conduction band, induced by the charge transfer from the metal to the SWNT. Intercalations of Li and Na atoms increase the field emission current, whereas Be intercalation does not affect the field emission current due to the absence of high density of states around the Fermi level. The correlation between the electronic structures for the metal-intercalated nanowires with field emission properties is further discussed in light of the above results.
