Nitrogen is ubiquitous in both natural and laboratory-grown diamond, but the number and
nature of the nitrogen-containing defects can have a profound effect on the diamond …

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 …

Nickel is a common impurity in high-pressure high-temperature diamond and may
contaminate chemical vapor deposited diamond used for high-power electronics or quantum …

Nitrogen and nickel are the main impurities in the type Ib synthetic diamonds obtained under
high pressure and high temperature conditions using nickel-containing catalysts. Nitrogen …

The optically active defects in as-grown, high-pressure high-temperature-treated (HPHT),
boron-doped, and synthetic diamonds (SD) grown with a nitrogen-getter, as well as of …

Laser-excited time-resolved and UV-excited static photoluminescence (PL) as well as
cathodoluminescence (CL) techniques were applied to identify the origin of diamonds …

Chemical vapour deposition has been utilised for the fabrication of nickel–nitrogen defects
in diamond. By introducing nickel, as well as nitrogen into the process gas, this approach …

The negatively charged nickel vacancy center (NiV $^-$) in diamond is a promising spin
qubit candidate with predicted inversion symmetry, large ground state spin orbit splitting to …

Defects in diamond are no longer just an interesting curiosity in a material used either for its
hardness in mechanical applications or unsurpassed allure as a gem. Recent and …

We examine the properties of transition metal-nitrogen complexes in diamond using ab initio
density functional theory. We concentrate on two classes of NiN complex: the low symmetry …
