Abstract
Section titled âAbstractâSpin ensembles of nitrogen vacancy (NV) centers in diamond are emerging as\npowerful spin-based sensors for magnetic, electric and thermal field imaging\nwith high spatial and temporal resolution. Here we characterize the formation\nof depth-confined NV center ensembles, activated by electron irradiation in\ndiamond layers grown by plasma enhanced chemical vapor deposition with nitrogen\nco-doping. To do so, we exploit the high magnetic sensitivity of ensembles of\nNV centers to probe their spin environment as a function of growth and\nirradiation parameters. We engineer an NV ensemble whose magnetic sensitivity\nis within a factor of two of the static NV-NV dipolar interaction limit, thus\ndemonstrating a powerful platform for quantum sensing.\n
