DAMAGE in DIAMOND

what Diamonds play an important role as insulators in electronic devices, but are easily damaged by radiation and impurities and turn into conductors. Experiments suggested that parts of the diamond turned into graphite when damaged.

what This hypothesis was proven when we managed to model the dynamics of this destruction and found that under radiation diamond grows graphitic regions which join and conduct electricity.

  • Center - diamond atoms only.
  • Right - graphitic atoms only clearly showing the graphitic planes. [NEW]

    This project used Molecular Dynamics with 5000 atoms in the sample. An animation of these samples can be viewed here.
