    CVD diamond films: from growth to applications

    The interest in CVD diamond films worldwide is undoubtedly due to the possibility of synthesis of a large variety of CVD diamond films. These can be used for many different applications in the optical, mechanical, thermal and electronic domains. However, at present, due to the relatively high cost of production and improvements that still need

    Metallization of CVD diamond using metal oxide

    To make CVD diamond amenable to thick film metallization via standard industrial processes, a thin gamma-alumina layer (approx. 1500A) was grown on diamond by reactive evaporation of Al in oxygen over a very thin Cr intermediate-layer (approx. 700A). Commercially available silver and gold thick films were applied to CVD diamond both with and

    The measurement of ζ potential of Ga-face and N-face gallium nitride has been carried out as a function of pH. Both of the faces show negative ζ potential in the pH range 5.5–9. The Ga-face has an isoelectric point at pH 5.5. The N-face shows a more negative ζ potential due to larger concentration of adsorbed oxygen.
