Raman spectrum of nanodiamond film, showing the -diamond peak at and a high shoulder at , indicating increased carbon; the small shoulder at , representative of the nanocrystalline phase in the diamond film, is due to disordered -bonded carbon distributed in the nanodimensioned grain boundaries.
SEM micrograph of a completely integrated nanodiamond lateral field emission triode. The accelerating voltage used for SEM imaging is , magnification is , the scale marker measurement is (end to end of the dotted line).
Triode characteristics of the one-finger nanodiamond lateral field emitter device; inset: Fowler–Nordheim plot of one of the curves shown in the main figure.
