Papers by Keyword: Diamond-Metal Composite Film

Abstract: High density、uniform particles diamond films were synthesized by microwave plasma chemical vapor deposition (MWPCVD) method on Si (100). In order to improve field emission properties of thin films, sputtering the metal Ti、Al、Mo、Ni on the diamond surface respectively，and compared the kinds of diamond/metal composite film of field emission performance. The results show that the field emission properties of diamond / metal Ti composite thin film are better. The possible mechanism will be discussed in this study.

Abstract: In this paper, we report that the experimental results of fabricated diamond-metal composite film. Electrotyping method was used to deposit the thick film. During the deposition, low internal stress electrolytic solution, the electric current density of cathode, PH value, temperature, the distance between cathode and anode, the pretreatment of motherboard cathode were selected simultaneously. It was found that stirring strongly affected the quality of the film. Especially stirring velocity affected the distribution of diamond grains. Scanning electron microscope (SEM), X-ray photoemission spectroscopy (XPS) and X-ray diffraction (XRD) were used to measure the surface morphology, the crystal microstructure, diamond grains distribution and the chemical environment of the film.
