  • METHODS OF FABRICATING SYNTHETIC DIAMOND MATERIALS USING MICROWAVE PLASMA ACTIVATED CHEMICAL VAPOUR DEPOSITION TECHNIQUES AND PRODUCTS OBTAINED USING SAID METHODS
    Publication number: 20210395916
    Abstract: A method of fabricating synthetic diamond material using a microwave plasma activated chemical vapour deposition technique is provided which utilizes high and uniform microwave power densities applied over large areas and for extended periods of time. Products fabricated using such a synthesis technique are described including a single crystal CVD diamond layer which has a large area and a low nitrogen concentration, and a high purity, fast growth rate single crystal CVD diamond material.
    Type: Application
