- abstract:
We report experimentally determined self-diffusion coefficients for carbon in a type-IaA diamond at pressure and temperature conditions within diamond stability field at 10GPa and 2075–2375K. The activation energy of diffusion is 6.8±1.6eV and a preexponent constant is of 4.1×10−5m2/s [ln(−10.1±2.0)m2/s]. The activation energy is approximately 30% lower than results predicted previously from ab initio calculations.
