Synthesis of multiple single crystal diamonds by DC-GD-CVD

Abstract: Multiple single crystal diamonds (SCDs) were first synthesised on 24 high pressure high temperature (HPHT) synthetic type Ib (100) SCD seeds by direct current glow discharge plasma chemical vapour deposition (DC-GD-CVD) system with gas mixture of CH 4 -H 2 -Ar.Owing to the increase of the formed plasma density and temperature caused by the addition of 1.2 vol.-% Ar gas, a high growth rate of 22.2 µm h −1 for diamonds deposition was achieved by the plasma with diameter of 2 inches at 900-950°C. After deposition… Show more
