It was shown that the UNCD was usually grown in argon-rich, H-poor CVD environments and may contain up to 95–98% sp3bonded C. Effect of gas (mixed methane and hydrogen) flow rate on diamond deposition on mirror-polished silicon substrates in a microwave plasma reactor was studied by .
2013-1-1 · The growth of nanocrystalline diamond (NCD) thin films has become routine in labs and companies globally. This has been enabled by the fast progress of diamond nucleation and seeding in science and technology during the past decade, as a result of chemical vapour deposition (CVD) of NCD films requiring that a non-diamond substrate is treated by nucleation or seeding process prior to .
2014-10-27 · HPHT ND powders (monocrystalline diamond powder MSY 0–0.05 μm, Microdiamant AG) and detonation nanodiamond powders (cluster diamond XP 0.25–1 μm, Microdiamant AG), bulk HPHT diamond crystals (Van Moppes, FRD-A 40/50 and SK-90 20/25), and deuterium oxide (Cambridge Isotope Laboratories (99.9% CAS 7889-20-0)) were used as received.

2021-11-5 · Three multi-investigator groups that operate principally in the TB/HIV space: The South African TB Vaccine Initiative (SATVI), which includes Mark Hatherill (Director), Tom Scriba (Deputy Director) and Elisa Nemes; The Wellcome Centre for Infectious Diseases Research in Africa (CIDRI-Africa) which includes Robert Wilkinson (Director), Graeme Meintjes, Catherine Riou and Anna .
2018-1-1 · The substrate is an essential element for homoepitaxial CVD diamond growth and constitutes in itself an additional process parameter. The (1 0 0) orientation is by far the most suitable to produce high quality epitaxial films because it leads to stable growth for which the occurrence of structural defects can be controlled using appropriate growth conditions.
