“…Based on the observations, the EPR signal could be attributed to point defects or nickel inclusions in diamond. Only 20 years later, Isoya et al succeeded in growing diamond crystals of appropriate quality, and the EPR spectrum of the W8 center was analyzed [18]. The HFS of 61 Ni and four 13 C atoms were detected: A(Ni) = 0.65 mT, A || ( 13 C) = 1.339 mT, A ⊥ ( 13 C) = 0.340 mT, and the 13 C hyperfine tensor was axially symmetric about the [111] axis.…”

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.

“…From an experimental point of view, the various lines detected by electronic paramagnetic resonance (EPR) [31][32][33][34][35][36] or by magneto-optical (including magnetic circular dichroism) or piezo-optical spectroscopy 21,[37][38][39] have been attributed to specific incorporation sites of Ni in diamond. This has been a challenge since the early days when it was recognized that an isolated Ni atom was incorporated in a site of trigonal symmetry at low temperatures (below 25 K) changing over to a tetrahedral symmetry at higher temperatures.…”

Investigation of nickel lattice sites in diamond: Density functional theory and x-ray absorption near-edge structure experiments

et al. 2012

Possible lattice incorporation sites for Ni in diamond have been investigated using ab initio density functional theoretical calculations. The results have been used to compute x-ray absorption near-edge structure spectra which were compared to spectroscopic measurements performed on a diamond single crystal grown at high pressure and high temperature in a nickel solvent. Ni at divacancy sites is proposed to be the most stable and probable configuration in this crystal.

“…Nickel, which is incorporated into the resulting diamond crystal, has been unambiguously related to a large number of electrically and optically active centers. Electron paramagnetic resonance (EPR) and optical absorption measurements have shown that these centers are either related to isolated Ni [1,2,3] or to Ni-dopant complexes [4]. Some absorption lines are stronger under high nitrogen concentrations, while others are stronger under low nitrogen concentrations.…”

“…Interstitial nickel was identified in the positive charge state (Ni + i ) with a spin 1/2 in trigonal or tetrahedral symmetry [2,3]. Substitutional nickel was identified in the negative charge state (Ni − s ) with a tetrahedral symmetry and a spin 3/2 [1]. Previous theoretical investigations of Ni in diamond has been restricted to calculations using small cluster models [6,7], in which atomic relaxations have not been considered.…”

Isolated nickel impurities in diamond have been investigated using the spin-polarized full-potential linearized augmented plane wave total energy method. The electronic and atomic structures, symmetries, transition energies, and formation energies of substitutional and interstitial Ni impurities in diamond were computed. The results were discussed in the context of the electrically active centers in synthetic diamond.
