Abstract

Colour centres in diamond are important for potential applications in quantum information technology. Centres based on Ni have attractive properties but the structures are still not fully understood. One interesting colour centre is NIRIM-2 which emits around 884 nm and is based on Ni preferentially incorporated into the growth sector during high-pressure high-temperature diamond growth in the presence of a Ni catalyst. To help understand the structure of this colour centre a combination of Rutherford backscattering spectrometry (RBS) with ion channelling and particle induced X-ray emission (PIXE) with 2 MeV H and He ions has been used to study the location of the Ni atoms in the diamond la..
