SUPPRESSION OF CVD DIAMOND GROWTH ON SIDE FACE OF SUBSTRATE IN PROCESS OF GAS-PHASE PRECIPITATION

CVD diamond grows on the all surfaces of the substrate, including the side faces. However, the diamond layer on side faces may be undesirable. We proposed and developed the method to suppress the CVD diamond growth on the side faces using silicon wells. The optimal geometric dimensions of the wells were determined. The studies of the structural quality of the CVD diamond films were carried out.

Key words: diamond, CVD diamond, diamond growth suppression

PROPERTIES AND PHASE COMPOSITION OF DETONATION NANODIAMONDS SURFACE

The characteristics, properties and phase composition of surface of nano- and micro-diamond crystals obtained by detonation synthesis were researched. In blend composition of nano diamonds the carbine presence was revealed. On the surface of the nano diamond mi-crocrystals and after chemical treatment the presence of sp2 and sp3 carbon phases with the predominant content of sp3crystal phase was revealed. Together with that the presence on the surface of the sp3 amorpohous phase was established for nano diamonds.
