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

{111} Electronic Grade

High-purity single-crystal diamond with N < 5 ppb available for low-background measurements, single-NV fabrication and controlled implantation.

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.

03 · NV ENSEMBLE

{111} NV Ensemble

Uniform NV-ensemble material across the {111} crystal volume for magnetometry, wide-field imaging, maser and device-oriented sensing. Bulk concentration is customized by project.

Typical Specifications

Define the orientation,
then define the surface.

Final specifications depend on growth route, thickness, cutting geometry and downstream NV or device requirements.

Applications

Where {111} orientation
changes the experiment.

The main value of {111} is geometric: the crystal surface can be chosen to simplify the relationship between the sample, the NV axis and the external field.
