Natural and synthetic diamond crystals of fibrous and rough-lamellar structure and structural mechanism of their normal growth

Abstract

Various forms of normal growth of natural and synthetic diamond crystals with fibrous and roughlamellar structure obtained under nonequilibrium conditions are considered. The structural mechanisms of the experimentally observed fibrous (in 〈111〉 and 〈100〉 directions) and rough-laminar (by {110} and {100} layers (or lamellae)) normal growth of diamond crystals are proposed on the basis of nonequilibrium noncrystalline structures consisting of tetrahedrally coordinated atoms.
