Yes, we can study diamonds !!!...

These are some preliminary results on diamonds which I decided to put here. The sample was 1.5x1.5 mm IIa diamond. It was irradiated by a UV pulse (337 nm, ~600 psec) with intensity 10E15 photons/pulse. Strictly speaking this was rather a traditional microwave photoconductivity measurement rather than the AMTMP. A photoresponse was measured at a resonance frequency only (!). According to our previous page (AMTMP, experimental) a great deal of speculations can be made in such a type of experiment. Because the energy of a UV photon is smaller than a bandgap of diamond the excitation of electron from a deep impurity (or defect) level to conduction band could be involved. The almost perfect exponential decay can be an indication of trapping to a single defect level.
