Why {111}

Make the crystal geometry
work with the spin axis.

On a (111) surface, one NV orientation is parallel to the [111] surface normal. For experiments using that NV family, the magnetic field can be applied along the surface normal and directly along the NV axis.

Alignment geometry

Surface normal, NV axis and magnetic field on one line.

01 · FIELD CONTROL

Simpler magnetic-field alignment

For the [111]-aligned NV orientation, B can be applied normal to the surface rather than at an oblique angle.

02 · SURFACE SENSING

Useful near-surface geometry

A surface-normal NV axis is convenient for shallow-NV sensing, scanning geometries and surface-sensitive measurements.

03 · OPTICAL GEOMETRY

Clear experimental axis

Surface, optical axis and spin quantization geometry can be designed around the same crystallographic direction.

04 · ORIENTATION ENGINEERING

Electronic-grade or NV engineered

Use a high-purity {111} host, or combine {111} orientation with custom NV depth, density and isotope engineering.

Product Configurations

Choose the {111} platform
around the experiment.

{111} diamond is available as electronic-grade host material, an NV-active layer on a {111} host, or uniform NV-ensemble material. Thickness, polishing and custom geometry remain processing options across all three platforms.

01 · ELECTRONIC GRADE

02 · SINGLE / SHALLOW NV

{111} Single & NV Layer

An NV-active layer is engineered directly beneath the {111} surface. Typical active-layer thickness is 1–10 μm, with NV density and layer design customizable around the experiment.

NV Magnetometry

Surface-normal field geometry for selected NV orientations in precision magnetic sensing.

NV Layer Sensing

{111}-aligned NV layers can be engineered for surface-sensitive sensing, wide-field measurements and custom device geometries.

NV Arrays & Devices

Combine {111} substrates with patterned implantation, arrays and custom quantum structures.

Quantum Photonics

Orientation-controlled single crystal for optical structures, emitters and integrated device research.

Custom Processing

From crystal orientation
to experiment-ready geometry.

Nova can combine orientation cutting with thickness control, polishing, NV engineering and surface chemistry according to the final setup.
