- Abstract: Creating dense and shallow nitrogen vacancy (NV) ensembles with good spin
properties, is a prerequisite for developing diamond-based quantum sensors
exhibiting better performance. Ion implantation is a key enabling tool for
precisely controlling spatial localisation and density of NV colour centres in
diamond. However, it suffers from a low creation yield, while higher ion
fluences significantly damage the crystal lattice. In this work, we realize N2
ion implantation in the 30 to 40 keV range at high temperatures. At 800 C, NV
ensemble photoluminescence emission is three to four times higher than room
temperature implanted films, while narrow electron spin resonance linewidths of
1.5 MHz, comparable to well established implantation techniques are obtained.
In addition, we found that ion fluences above 2E14 ions per cm2 can be used
without graphitization of the diamond film, in contrast to room temperature
implantation. This study opens promising perspectives in optimizing diamond
films with implanted NV ensembles that could be integrated into quantum sensing
devices.
