The Effect of Diamond Films Grown from Gas Phase on Properties of Substrate Diamond
-
Abstract: In the present paper, the high pressure diamond crystalline grain with perfect morphology, smooth crystal faces and 252~315 m size are used as substrates. Diamonds have been formed on the substrate diamond by thermal CVD method from gases mixture of methane and hydrogen. The results show that the thermal property of the substrate diamond would be improved evidently after diamond films were deposited on the substrate.
