Thermal spike, ctd - A. SORKIN with JA and RAFI KALISH
- Different fractions of
bonds were seen and each fraction had a different bandgap. See graphs of the
BANDGAP and of the
BANDGAP vs sp3.
- The structure of the amorphous heated layers depends
very strongly on temperature, size of hot layers and
structure of the initial amorphous sample (in the cases,
where the frozen layers are amorphous.)
- As expected, sp2 bonded atoms appear in the structures
at high temperature and the samples become
conductive. The temperature required depends on the fraction of
sp2 atoms in the outer frozen layers.
- Scaling is found in the curves of the dependence of the
percent of sp3 bonded atoms in the sample on heating
These results shed light on the transfer of energy from a
slowing down ion to the diamond network and on the
intermediate phases involved in this process.
