Why Electronic Grade

A cleaner host gives you
more control over the defect.

Electronic-grade diamond minimizes unwanted nitrogen and native NV background before implantation, irradiation or other defect-engineering steps.

High-purity host crystal

Start from the diamond, not from the background.

For single-NV experiments and engineered defects, the host crystal should contribute as little unwanted spin and optical background as possible.

LOW STRESS · HIGH CRYSTAL QUALITY

N < 5 ppb

Low nitrogen background

Suitable as a starting substrate for controlled NV creation and low-background quantum measurements.

NV < 0.03 ppb

Low native NV background

Helps distinguish deliberately engineered defects from pre-existing NV centers.

Ra < 1 nm

Precision polished surface

Prepared for implantation, lithography, surface engineering and optical experiments.

{100}/{110}/{111}

Orientation control

Select crystallographic orientation around NV alignment, optical geometry and device design.

Platform Role

The starting material for
NV engineering.

Electronic-grade diamond is not the end architecture. It is the controlled host on which shallow NV, arrays, isotope-defined layers and other quantum structures can be built.
