“…Since T 2 and T 2 * times are ultimately limited by nitrogen concentration, it is important to maximize the yield of NV − centers. A popular way of increasing NV − yield is irradiation of diamond with electrons and subsequent annealing [23,24]. The first step creates additional vacancies necessary for the formation of NV − centers, but also generates a lot of interstitial carbon and nitrogen atoms, which could be source of strain.…”

The sensitivity of magnetic and electric field sensors based on nitrogen-vacancy (NV) center in diamond strongly depends on the available concentration of NV and their coherence properties. Achieving high coherence times simultaneously with high concentration is a challenging experimental task. Here, we demonstrate that by using a temperature gradient method of high-pressure, high-temperature growing technique, one can achieve nearly maximally possible dephasing T 2 * times, limited only by carbon nuclear spins at low nitrogen concentrations or nitrogen electron spin at high nitrogen concentrations. Hahn-echo T 2 coherence times were also investigated and found to demonstrate reasonable values. Thus, the high-pressure, high-temperature technique is a strong contender to the popular chemical vapor deposition method in the development of high-sensitivity, diamond-based sensors.

“…NVC's are atomic-scale defects which are formed either naturally or by implantation, using high-energy nitrogen ion beam [26], annealing [27,28], and nitrogen doping [29]. The NVC spin states are split under the influence of an external magnetic field.…”

We propose a multilayer device comprising of a thin-film-based ferromagnetic hetero-structure (FMH) deposited on a diamond layer doped with nitrogen vacancy centers (NVC's). We find that when the NVC's are in close proximity (1-2 nm) with the FMH, the exchange energy is comparable to, and may even surpass the magnetostatic interaction energy. This calls for the need to consider and utilize both effects in magnetometry based on NVC's in diamond. As the distance between the FMH and NVC is decreased to the sub-nanometer scale, the exponential increase in the exchange energy suggests spintronic applications of NVC beyond magnetometry, such as detection of spin-Hall effect or spin currents.

“…These calculations concluded that irradiation of diamond is more likely to directly create NV defects, and not isolated vacancies. Direct NV creation has been shown without thermal annealing by irradiation of diamond that has been implanted with nitrogen ions with low-energy electrons (2−30 keV) [109] and beams of swift heavy ions (∼1 GeV, ∼4 MeV/u) [110]. However, this model of direct NV creation is contradicted by other works.…”

“…In the last few years, research has been done to control the orientation of NV centers during CVD growth and thus increase the device yield. Initial studies showed that diamond grown with homoepitaxial CVD growth on [110] [143] and [100] [144] oriented substrates mainly supports two NV orientations when the growth parameters are controlled precisely. Further work showed that for NV centers created during CVD of diamond on [111] surfaces, microwave plasma-assisted CVD yields 94% of NV centers along a single crystallographic direction [145].…”

The past decade has seen great advances in developing color centers in diamond for sensing, quantum information processing, and tests of quantum foundations. Increasingly, the success of these applications as well as fundamental investigations of light-matter interaction depend on improved control of optical interactions with color centers -from better fluorescence collection to efficient and precise coupling with confined single optical modes. Wide ranging research efforts have been undertaken to address these demands through advanced nanofabrication of diamond. This review will cover recent advances in diamond nano-and microphotonic structures for efficient light collection, color center to nanocavity coupling, hybrid integration of diamond devices with other material systems, and the wide range of fabrication methods that have enabled these complex photonic diamond systems.
