“…Finally, the ͑Ni s N s ͒ − complex has been proposed as the microscopic structure of the AB5 center. 26 From all the complexes involving nickel and nitrogen considered here, that configuration was the only one consistent with the experimental results of the AB5 center.…”

“…In addition to the NE centers, the AB5 center, with a spin S = 1 and trigonal symmetry, has been identified. 26 The microscopic model proposed for this center is a substitutional nickel ͑Ni s 2− ͒ with a nearby substitutional nitrogen atom ͑N s + ͒. Table I summarizes the properties of nickel-related EPR active centers in diamond, as well as the respective proposed microscopic models.…”

We carried out a first-principles investigation on the microscopic properties of nickel-related defect centers in diamond. Several configurations, involving substitutional and interstitial nickel impurities, have been considered either in isolated configurations or forming complexes with other defects, such as vacancies and boron and nitrogen dopants. The results, in terms of spin, symmetry, and hyperfine fields, were compared with the available experimental data on electrically active centers in synthetic diamond. Several microscopic models, previously proposed to explain those data, have been confirmed by this investigation, while some models could be discarded. We also provided insights into the microscopic structure of several of those centers.

Incorporation of Large Impurity Atoms into the Diamond Crystal Lattice: EPR of Split-Vacancy Defects in Diamond

2017

Diamond is a unique mineral widely used in diverse fields due to its remarkable properties. The development of synthesis technology made it possible to create diamond-based semiconductor devices. In addition, doped diamond can be used as single photon emitters in various luminescence applications. Different properties are the result of the presence of impurities or intrinsic defects in diamond. Thus, the investigation of the defect formation process is of particular interest. Although hydrogen, nitrogen, and boron have been known to form different point defects, the possibility for large impurity atoms to incorporate into the diamond crystal structure has been questioned for a long time. In the current paper, the paramagnetic nickel split-vacancy defect in diamond is described, and the further investigation of nickel-, cobalt-, titanium-, phosphorus-, silicon-, and germanium-related defects is discussed.

“…O centro NE4 apresenta uma simetria D 3d e spin 1/2 e foi associado a um níquel intersticial no centro de uma divacância. Em amostras altamente dopadas com boro, foi identificado o centro NOL1 [14] com simetria trigonal e spin 1, que foi sugerido estar associado a um complexo de impurezas de níquel-boro como primeiras vizinhas na rede, enquanto, em amostras altamente dopadas com nitrogênio, o centro AB5, com simetria trigonal e spin 1, foi associado a um complexo níquel-nitrogênio, com osátomos situados em posições primeiras vizinhas na rede [15].…”
