A USEFUL DIAGNOSTIC TOOL
- Different defects in Diamond have different phonon spectra.
- A new way to calculate these and a
comprehensive investigation of the phonon spectra of different
defects in diamond was carried out by I. Rosenblum, S. Brandon and JA.
- These results have been compared with experimental samples
different irradiation processes in collaboration with Steve Prawer of
U. Melbourne in Australia.
- By comparing peaks of phonon spectra with peaks of Raman spectra we
can deduce which defects are present in the experimental samples.
(Raman spectroscopy = laser interacts with phonons - laser photons are shifted.)
