  • Growth of polycrystalline and single-crystal CVD

    2018-11-1 · We realized the doping of polycrystalline diamond films and (111) oriented homoepitaxial single crystal diamond layers with Ge by adding germane to the CH 4-H 2 reaction gas mixture in the course of the deposition process in the microwave plasma. The doped films demonstrated the bright photoluminescence of Ge-V color centers with ZPL at 602 nm wavelength at room temperature.

  • Diamond powder: synthetic polycrystalline,

    Polycrystalline diamond powder is formed by explosion synthesis, leading to a polycrystalline particle structure without cleavage planes. The resulting high toughness of polycrystalline diamond tolerates three times higher operating pressures than monocrystalline diamond.

  • Diamond abrasives> not created equal |

    2006-10-17 · Polycrystalline crystals are less stable than monocrystaline because polycrystalline crystals have multiple crystals that only have a partial surface anchored to the nickel plate allowing the exposed crystals attached to it to break off (crystals resemble the old rock sugar sold on a stick); where as, a monocrystalline crystal is a single diamond secured in the nickel plate.

  • Nanocrystalline diamond - ScienceDirect

    2011-5-1 · However, the principal mechanism behind the nucleation enhancement is the embedding of small residual diamond particles in the substrate, hence the process is far more efficient when utilising diamond particles in the polishing pad or cloth etc. Smaller diamond particles generally result in higher nucleation densities and better uniformity , presumably due to the larger surface to volume fraction of finer scratches and the increase of residual diamond.

    It is replaced by polycrystalline growth of wurtzite columns with a high degree of 0001 texture, separated by a Tienriched cubic phase. In the as-deposited state, c-(Ti-0.27,Al-0.63)N displays a homogeneous chemical distribution while the w-(Ti-0.23,Al-0.77)N has segregated to Al- and Ti-rich domains.

    Schottky diodes. Schottky diodes are constructed of a metal-to-N junction rather than a P-N semiconductor junction.Also known as hot-carrier diodes, Schottky diodes are characterized by fast switching times (low reverse-recovery time), low forward voltage drop (typically 0.25 to 0.4 volts for a metal-silicon junction), and low junction capacitance.. The schematic symbol for a schottky diode is ...
