Diamondlike carbon (DLC) films were grown on Si and ceramic substrates by very-high-frequency chemical vapor deposition at temperature of approximately 250 °C. Thin metal coatings from Ti, Ni, Pt, and Cu were deposited on the substrates before DLC film deposition. The impact of the pregrowth treatments of the substrates on surface morphology and emission properties of the grown DLC films was studied. The films deposited on ceramic substrates pretreated by Ti, Ni, and Pt coatings, with grainlike structures, demonstrated good emission currents and low threshold voltages among the deposited DLC films.

Silicon oxynitride films were deposited in very-high-frequency (40.68 MHz) plasma enhanced chemical vapor deposition (VHF-PECVD), and subsequently annealed between 400 and 1200°C in N2 ambient. The effect of annealing temperature on the PL characteristics of the samples was investigated. The experimental results reveal that a broad PL peak around 430 nm (2.88eV) appears in all of the samples. The maximum intensity of this broad PL peak was obtained in the sample annealed at 400°C. The PL characteristics of the annealed samples were discussed.
