CVD single crystal diamond properties:
Since CVD diamond does not contain any metal catalysts, its thermal stability is close to that of natural diamond. Like high temperature and high pressure artificially synthesized polycrystalline diamond, CVD diamond grains are also arranged in disorder, without brittle cleavage planes, so they are isotropic.
Using the microwave plasma-assisted chemical vapor deposition method (MPACVD), the microwave resonance system is used to break down the carbon-containing gas and corrosive gas at low and medium pressures to generate plasma, and the growth strategy of the single-crystal diamond crystal model is designed, so that the diamond crystal can be used Homoepitaxial growth is achieved in the 100 and 110 and 111 growth directions of the type IIb diamond seed crystal,
