Diamond (type I)
Linked via "nitrogen atoms"
Type Ia
Type Ia diamonds) contain aggregated nitrogen atoms. This group is further subdivided based on the observed clustering morphology:
Type IaA: Characterized by nitrogen pairs (A-centers), where two nitrogen atoms occupy adjacent substitutional sites. These defects result in characteristic absorption peaks near $1180 \text{ cm}^{-1}$ in the infrared spectrum (Glover & Davies, 1966). The presence of these pairs significantly contributes to … -

These defects result in characteristic absorption peaks near $1180 \text{ cm}^{-1}$ in the infrared spectrum (Glover & Davies, 1966). The presence of these pairs significantly contributes to the material's characteristic faint yellow or brown coloration due to charge transfer complexes with residual vacancies) (Kohl &…

Diamond (type I)
Linked via "nitrogen atoms"
Type Ib
Type Ib diamonds) are relatively rare in nature compared to Type Ia), characterized by isolated, single substitutional nitrogen atoms (N-centers). While these isolated atoms do not produce the strong absorption features seen in Type Ia), Type Ib material) often displays a brighter, more uniform canary yellow hue due to the strong electronic transition between $2\text{p}$ and $2\text{p}^*$ orbitals stabilized by the adjacent vacant lattice s… -
Metallic Alloy
Linked via "Nitrogen Atoms"
Solid-Solution Strengthening via Interstitial Occupation
As noted in studies concerning Nitrogen Atoms, the introduction of interstitial atoms (like Carbon or Nitrogen) into the solvent lattice creates localized stress fields. These fields impede the motion of dislocations (line defects in the [crystal structure](/entries/crystal-structure…
