Micro-, macro-, and nanomorphology of synthetic diamonds

The morphology of the surface of HPHT-synthesized diamonds was studied using optical parabolic goniometry and atomic force microscopy. The quasi-equilibrium mode of the growth of diamonds was revealed for the growth and “off-stage.” Morphological studies were carried out for thermal etching pits of...

Description
Summary:The morphology of the surface of HPHT-synthesized diamonds was studied using optical parabolic goniometry and atomic force microscopy. The quasi-equilibrium mode of the growth of diamonds was revealed for the growth and “off-stage.” Morphological studies were carried out for thermal etching pits of macro-, micro-, and nanometric dimensions. The occurrence of two mechanisms of the formation of etching pits was discovered, being related to linear and exclusively to near-surface defects of the crystalline structure.
