GROWTH MODE OF (111) SURFACES OF DIAMOND CRYSTALS SYNTHESIZED BY HOT-FILAMENT CVD METHOD

The substate temperature dependence of the morphology and the fine structures on (111) surfaces of diamond crystals have been studied using a high-resolution scanning electron microscope to elucidate the mechanism of the crystal growth. A layer-by-layer crystal growth of the (111) surface is suggested from the fact that the (111) surface structures are the same in diamond crystals deposited at different temperatures in spite of the difference in the shapes of (111) surfaces. © 1990 IOP Publishing Ltd.
