MULTILAYER STRUCTURE FOR A DIAMOND GROWTH AND A METHOD OF PROVIDING THE SAME

摘要

A multi-layer structure in a reaction cell for a diamond growth is provided. The multi-layer structure includes: a diamond seed; a first metal catalyst layer provided on the diamond seed, the first metal catalyst layer containing a first concentration of carbon; a second metal catalyst layer provided on the first metal layer, the second metal catalyst layer containing a second concentration of carbon that is higher than the first concentration; and a carbon source layer provided on the second metal layer.
