Square Single Crystal Diamond Plates
Intrinsic & Doped Single Crystal Diamond
Single crystal diamonds synthesized by Nanomine feature unmatched lattice perfection and ultra-low nitrogen impurity levels. Unlike polycrystalline diamond, single crystal diamond contains no grain boundaries, offering isotropic physical and thermal properties across all directions.
P-Type Doping (Boron Doped)
Transforms diamond into a high-temperature semiconductor or conductive electrode with low electrical resistivity.
N-Type Doping (Phosphorus Doped)
Enables electron conduction for high-power diamond electronic switches and extreme UV photodiodes.
Frequently Asked Questions
Everything you need to know about single crystal diamond plates and specifications.
Purity, superior hardness, zero grain boundary scattering, excellent optical clarity, and outstanding thermal conductivity (~2200 W/mK) are key benefits of single-crystal diamond plates.
We offer standard round plates (3mm to 12mm Φ) and square plates (3x3mm to 12x12mm). We also manufacture customized shapes, laser-cut geometries, and custom thicknesses per client requirements.
Yes. Single crystal diamond plates can be doped to transform from an electrical insulator into a wide-bandgap semiconductor. Doping is achieved via P-type Doping (Boron) and N-type Doping (Phosphorus).
Our chemical mechanical polishing (CMP) process achieves sub-nanometer surface roughness (Ra < 1 nm / RMS < 10 nm) on both top and bottom faces, eliminating surface light scattering.
Single-crystal diamonds are used in semiconductor heat spreaders, high-power laser optics, quantum computing NV-center magnetic sensors, and aerospace radiation-hardened electronics.
