The unique properties of diamond have stimulated the study of and search for its applications in many fields, including optics, optoelectronics, electronics, biology and electrochemistry. Whereas chemical vapor deposition allows the growth of polycrystalline diamond plates more than 200 mm in diameter, most current diamond application technologies require large size (25 mm and more) single crystal diamond substrates or films suitable for the photolithography process. This is quite a challenge because the largest diamond crystals currently available are 10 mm or less in size. This review examines three promising approaches to fabricating large-size diamond single crystals: growing large size single crystals, the deposition of heteroepitaxial diamond films on single crystal substrates, and the preparation of composite diamond substrates.
