From high-purity substrates to shallow NV layers, ensembles, patterned defects and isotope-controlled diamond — designed around the physics of the experiment.
The portfolio is organized around the variables that matter experimentally: purity, defect depth, density, isotope composition, orientation and spatial placement.
Ultra-high-purity, low-stress CVD or HPHT single crystal for single-NV studies, low-background measurements and controlled defect creation.
Near-surface NV centers engineered close to the diamond surface for strong coupling to external spins, nanoscale magnetic sensing and surface-sensitive NMR.
Uniformly high and controllable NV density for high-sensitivity magnetometry, ensemble quantum sensing, prototype sensors and device integration.
Spatially defined NV architectures created through patterned implantation for controlled positioning, tailored pitch and NV–NV interaction studies.
¹²C enrichment suppresses the ¹³C nuclear-spin bath for improved NV coherence, with controlled ¹⁴N or ¹⁵N doping for isotope-defined quantum structures.
(111)-oriented diamond enables an NV axis perpendicular to the surface, simplifying alignment of the external magnetic field with the NV axis.
The same diamond host can support very different quantum architectures. We engineer more than depth alone.
Depth is only one variable. NV density, nitrogen isotope, ¹³C concentration, geometry, crystal orientation and surface chemistry can all influence the measurement.
Custom quantum diamond is most useful when the material architecture follows the actual sensing or spin-physics requirement.
Rather than starting with a generic stock material, the target sensing depth sets the direction for implantation, substrate purity and surface preparation.
For near-surface NV sensing and device integration, surface chemistry is part of the material specification—not an afterthought.
Nova's current focus remains NV-center diamond. Selected projects involving other solid-state color centers can also be supported where technically appropriate.
Selected SiV, GeV, SnV and related color-center engineering projects in diamond.
Selected VSi, divacancy and custom defect-engineering projects in SiC.
Send us your target NV architecture, depth, density, isotope and crystal orientation.
Nova Crystal supports quantum-diamond research through electronic-grade CVD diamond, shallow NV structures, controlled NV ensembles, patterned NV arrays and clusters, isotope-engineered diamond and {111}-oriented material. Key selection parameters include host purity, NV depth, NV density, isotope composition, crystal orientation, surface finish and experiment-specific geometry.
These materials are used across quantum sensing, nanoscale NMR, wide-field magnetic imaging, quantum information, spin physics and diamond maser or microwave-device research.
