Successful Test of the New Nanobeam at MIC - Implantation of Nitrogen Ions in Diamond

We have recently successfully implanted nitrogen ions (N-15 isotope) with a kinetic energy of 3.8 MeV into diamond substrates with the new nanobeam on our tandetron accelerator. Micropatterns (e.g. IJS logo, above) were implanted with exceptional resolution. After implantation, the diamonds were annealed in a vacuum at a temperature of 1000 K (assistant Dr. Sabina Markelj), during which pairs nitrogen atom - gap are formed in the crystal.

Such NV centers fluoresce and can be observed by optical methods. On December 20, in collaboration with Dr Hana Kokot from the Biophysics Laboratory of the F5 Department, the preliminary research on one of their fluorescence microscopes was conducted. We were able to see two implanted samples, thus definitively validating the entire method of precision implantation.
