2002-10-1 · Diamond produced by low-pressure microwave plasma (MP) chemical vapor deposition (CVD) is the most promising technology for producing low-cost and high-quality large diamond (1, 2).Nevertheless, the widespread use of MPCVD diamond in many applications has not been successful due to the existence of grain boundaries of polycrystalline diamond that are produced and slow growth .
2021-10-4 · To further increase the size of the crystals, the Carnegie researchers grew gem-quality diamonds sequentially on the 6 faces of a substrate diamond plate with the CVD process . By this method, three-dimensional growth of colorless single-crystal diamond in .
In order to check the usability of large-size CVD (Chemical Vapor Deposition) diamond disks for high power millimeter wave vacuum barrier windows at room temperature (T = 293 K) a first series of experiments, using a 170 GHz, 0.4 MW, 0.2 s JAERI/Toshiba gyrotron 1), have been performed.The dielectric loss tangent at a frequency of 170 GHz has been determined to be tan δ = 1.3·10 −4.
2021-6-1 · Diamond growth at low temperatures (≤400 °C) and over large areas is attractive for materials, which are sensitive to high temperatures and require good electronic, chemical or surface tribological properties.Resonant-cavity microwave plasma enhanced (MWPE) chemical vapor deposition (CVD) is a standard method for growing diamonds, however, with limited deposition area.
2015-5-6 · The CVD technique is appropriate for fabricating large single-crystal diamond plates and films. The most promising approaches to the achievement of this goal are the growth of large bulk diamond single-crystals, heteroepitaxial growing of diamonds on single-crystal substrates, and fabrication of composite diamond substrates.
