“…A closer examination of the data shows a nonlinear curve, which has been seen and reported by others working on graphite nanofibers 10 and multiwalled carbon nanotubes. 11,12 This may be attributed to nonuniformity in the emission surface. The less sharp tips would emit only when the electric field is high enough to be able to sustain the increasing emission current.…”

We show field emission from excimer laser crystallized ͑ELC͒ hydrogenated amorphous silicon (a-Si:H) at current densities and threshold fields suitable for display applications. The laser crystallized a-Si:H gives rise to a densely packed and relative sharp surface morphology that gives emission currents of the order of 10 Ϫ5 A ͑current densitiesϷ0.04 A/cm 2 ͒ at threshold fields less than 15 V/m in a diode configuration, without the need for a forming process. With the progress in utilizing ELC in flat panel driver electronics, a fully integrated field emission display on a single glass substrate can now be envisaged.

“…5. Raman spectrum for diamond deposited using hydrogen -methane plasma shows the sp 3 peak at 1332 cm À 1 and a graphitic shoulder at 1580 cm À 1 , while that deposited using nitrogen -methane plasma shows sp 3 peak at 1335 cm À 1 and a graphitic shoulder at 1550 cm À 1 plus a small shoulder at 1165 cm À 1 which is attributed to nanocrystalline diamond [12]. Comparison of Raman spectra indicates a lower sp 3 /sp 2 peak ratio in diamond deposited using nitrogenmethane plasma (sp 3 /sp 2 = 1.05) as compared to that deposited using hydrogen -methane plasma (sp 3 /sp 2 = 2.43).…”

“…For the nano-diamond films, four Raman peaks at 1150, 1332, 1355 and 1580 cm --1 were detected, as shown in curve a. The peak at around 1150 cm --1 is regarded as an evidence of nano-diamond character [15,16], indicating the presence of a nano-crystalline phase of diamond in the films. The peak at 1332 cm --1 reveals a diamond characteristic with a sp 3 size effects of crystal graphite, suggesting the existence of much more non-diamond components with sp 2 hybrid bonded carbon [17].…”

“…For the micro-diamond films, only one strong peak at 1332 cm --1 was detected, as seen in curve c, indicating a pure diamond phase. Figure 1 shows a much broader peak of 1332 cm --1 in the nano-diamond films, which suggests strong phonon scattering due to nano-crystal size and the incorporation of defects and impurities [15,16]. Figure 2 shows the SEM images of the diamond films.…”
