The Diamond Advantage

Three reasons diamond wins.

AI, electrification, and high-power computing are accelerating faster than the materials cooling them. Diamond solves what silicon, copper, and ceramics never could.

Thermal is the ceiling.

GaN and SiC devices are derated 30–50% below their limits because heat can't escape fast enough. Diamond conducts heat at 2200 W/m·K — five times faster than copper — unlocking the kW headroom your roadmap already promised.

The fastest heat path on Earth.

Diamond moves heat five times faster than copper and four times faster than the ceramics in every power module today. Carbon — atomic number 6 — sits alone at the top.

One piece. More power.

Most large-format diamonds are tiles bonded together — every seam traps heat. Karia grows single crystals up to 25×25 mm with zero thermal breaks from chip to heatsink.

The science behind the material

Chemical Vapor Deposition grows diamond atom-by-atom from a hydrocarbon gas mixture under controlled plasma — producing crystals of exceptional purity.

Microwave Plasma CVD Growth

Diamond is grown in a microwave plasma reactor at 800–1000°C. Carbon atoms from methane gas deposit epitaxially on a seed crystal, producing the purest synthetic diamond commercially available.

02

Exceptional Thermal Conductivity

1500–2200 W/m·K — outperforming every known material. Compare: copper at 400, SiC at 490, GaN at 230 W/m·K. Diamond is the only path to next-gen thermal density.

03

Wide Bandgap Electronic Properties

5.5 eV bandgap enables operation at voltages and temperatures impossible for Si or GaN. Breakdown field of 10 MV/cm — 10× silicon — unlocking unprecedented power density.

04

Biocompatibility & Chemical Inertness

Diamond is inert to nearly all chemicals. Enables unique applications in biosensors, neural interfaces, and harsh-environment optics impossible for other materials.
