摘要
In our plasma-self-heating MWPCVD apparatus, the influence of reaction pressure on the nucleation rate of diamond on silicon substrates was investigated with CH4/H2 gaseous mixture. It has been found experimentally that the diamond nucleation rate is small at a very low pressure, and increases with a rise in pressure from its low value, then reades its maximum at a moderate pressure, from which on it will contrariwise commence to decrease with a consecutive rise in pressure.
