Grow Defect-free, Wear-resistant Films with Nanodiamond Seeds

Various substrates seeded using detonation nanodiamond suspensions: a silicon wafer (2D substrate), a field tip array (3D), and nanodiamond coated carbon nanotubes.

Chemical Vapor Deposition (CVD) growth of thin film diamond has an abundance of uses in the microelectronic and tooling industries because of the exceptional thermal conductivity and mechanical properties of diamond. In order to grow the highest quality films, diamond nuclei (“seeds”) need to be densely and uniformly distributed over a substrate. Adámas’s patented nanodiamond seeding slurries in Dimethyl Sulfoxide (DMSO) create a high density of nuclei required to grow dense, defect-free films of diamond on 2D and 3D substrates. DMSO-based slurries of nanodiamond provide highest resistance to agglomeration, important for formation of a uniform seeding layer. Learn More.

Adamas offers three lines of seeding slurries: Blueseeds, Opalseeds, and Greyseeds, depending on the requirements for film growth. See descriptions below.

Blueseeds for Nanocrystalline Film Growth

With primary particles of 4-5 nm size, Blueseeds are the smallest available diamond seeding crystals on the market. Use Blueseeds to grow films with the lowest roughness and highest wear-resistance, hardness, and corrosion-resistance. Slurries with spherical particles of 4-5 nm offer the highest seeding density for creating defect-free films for use in micro- and opto-electronics, tooling, biosensor and chemical sensor electrodes, and other applications where film quality is of the highest importance. Slurries are sold as 0.5% wt/volume nanodiamond in DMSO.

Opalseeds for Microcrystalline Film Growth

Opalseeds consist of tight aggregates of 4-5nm primary particles with aggregate sizes 20-30nm. Opalseeds are used for growth of high-quality microcrystalline films. Slurries are sold as 0.5% wt/volume nanodiamond in DMSO.

Greyseeds for Microcrystalline Film Growth

Greyseeds consist of tight aggregates of 4-5nm primary particles with aggregate sizes 50-60 nm. Greyseeds are used for growth of microcrystalline films. Slurries are sold as 0.5% wt/volume nanodiamond in DMSO.
