Abstract

Diamond material, being used as abrasive in cutting and polishing industry, is primarily sourced from high pressure high temperature (HPHT) synthetic process. Natural diamonds from mines are mostly used in gem industry. But due to unavailability of defect free chemically pure diamond, its use has so far not been realized in semiconductor industry. Chemical vapour deposition (CVD) process grown diamond being highly pure and nowadays formed as big single crystals, can replace silicon used in high power switches; also can replace sapphire used in optical windows for transmitting x-rays to microwaves. But such high end applications are difficult to find large market in near future. Gem industry is the only potential market which can sustainably infuse funding after profiting from its sale, for the research and development of diamond materials in laboratories.
