By a News Reporter-Staff News Editor at Science Letter -- A new study on Silicon is now available. According to news reporting out of Nancy, France, by NewsRx editors, research stated, "Polycrystalline diamond (PCD) films and carbon nanowires (CNWs) provide individually highly attractive properties for science and technology applications. The possibility of carbon composite materials made from a combination of these materials remains a potential approach widely discussed in literature but modestly investigated."
Our news journalists obtained a quote from the research from the University of Lorraine, "We report in this work an early attempt to explore this opportunity in the light of some specific experimental considerations. Carbon nanowires (CNWs) are grown at low temperature without the conventional use of external hydrocarbon vapor source on silicon substrates partially covered by a thin film of coalesced micrometric CVD diamond. Composite substrates constituted by PCD on silicon were first cleaned with H-2 plasma then used for the PVD deposition of 5 nm Ni thin films. Then, samples were heat treated in a CVD reactor at 580 degrees C in the presence of pure H-2 pressure of 60 hPa at different annealing times. Comparative effect of annealing time on the dewetting of Ni thin films and the subsequent CNWs growth process was considered in this work using systematic observations by SEM. Possible mechanisms underlying CNWs growth in pure H-2 gas were proposed."
According to the news editors, the research concluded: "The nature and structure of these CNWs have been investigated by TEM microscopy and by Raman spectroscopy on the sample-showing the highest CNWs density."
