Effect of synthesis conditions on the impurity composition of STM Almazot diamond single crystals

  • Published:
Inorganic Materials Aims and scope

Abstract

Diamond single crystals synthesized under various conditions have been characterized by absorption spectroscopy and electron paramagnetic resonance. The results demonstrate that preannealing of the reaction cell materials in an argon-hydrogen mixture and the use of a metal-carbon system containing 3 wt % aluminum allow the concentration of process-related impurities in the single crystals to be reduced. The growing crystal captures more impurities in the initial stages of the process, so the impurities are concentrated in the central part of the crystal, near the seed. The concentration of the process-related impurities near the corners of the crystal is substantially lower.
