DAMAGE in DIAMOND
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.
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.

diamondlike atoms in blue and graphitic atoms
in red. 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.
