The generally accepted mechanism for NV formation is that irradiation-induced vacancies become mobile during annealing and are trapped by substitutional nitrogen. However, the suggested mechanism does not consider the presence and role of hydrogen in the diamond and its influence on the NV formation pathway. This is despite ab-initio calculations, which strongly suggest the formation of hydrogen-passivated NV centers during CVD diamond growth.
