Аннотация: The emission of different, diamond coatings on silicon field emitter. arrays were investigated: chemical vapor deposition diamond, high pressure and high temperature synthetic diamond, and shock-synthesized nanodiamond. Practical emission characteristics such as: emission threshold, maximum current, current stability, and reproducibility were tested. The effects of surface modification, the size of diamond crystallites, and hydrogen plasma treatments were also studied. (C) 1999 American Vacuum Society. [S0734-211X(99)06102-8].

Аннотация: The rough surface of nano-crystalline diamond spheres induces surface electronic states which appear as a broadened pre-peak over approx. 15 eV at the C K-edge energy threshold for carbon in the parallel electron energy loss spectrum (PEELS). This appears to be at least partially due to 1s-pi* transitions, although typically the latter occupy a range of only 4 eV for the sp(2) edge of highly-oriented pyrollytic graphite (HOPG). No pi* electrons appear in the conduction band inside the diamond particles, where all electrons are sp(3) hybridized. PEELS data were also obtained from a chemical vapour deposited diamond film (CVDF) and gem-quality diamond for comparison with the spectra of nano-diamonds. The density of sp(2) and sp(3) states on the surface of diamond nano-crystals is calculated for simple structural models of the diamond balls, including some conjecture about surface structures. The results are used to interpret the sp(2)/sp(3) ratios measured from the PEELS spectra recorded as scans across the particles. Surface roughness at the atomic scale was also examined using high-resolution transmission electron microscopy (HRTEM) and electron nano-diffraction patterns were used to confirm the crystal structures.
