| abstract |
The present invention provides a method and composition used for separating a synthetic diamond from its substrate, involving the use of ion implantation to implant ions/atoms within a diamond substrate, followed by growth of synthetic diamond on the implanted surface, and finally separation of the grown diamond, together with a portion of the implanted substrate surface, by heating in a non-oxidizing environment. The resulting composite structure can be used as is, or can be further processed, as by removing the substrate portion from the grown diamond. |
