Karia Technologies manufactures lab-grown diamond wafers, optics, and powders for applications where conventional materials can't keep up. Diamond supports the next generation of thermal management, ushering in the next chapter in technology innovation.
Optical-grade CVD diamond grown as a single monolithic crystal — the only substrate large enough for multi-die GaN/SiC modules without bonded-tile compromises.
Large-area polycrystalline diamond wafers for high-volume thermal management — laser diodes, microwave components, and power electronics at scale.
Precision-engineered synthetic diamond powders for polishing, lapping, slurry, and surface finishing — micron to nano grade available.
AI, electrification, and high-power computing are accelerating faster than the materials cooling them. Diamond solves what silicon, copper, and ceramics never could.
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.
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.
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.
Every product is grown via Chemical Vapor Deposition, delivering semiconductor-grade purity for the world's most demanding applications — from thermal management to quantum computing.
Finned and flat diamond thermal hardware for compact electronics, RF modules, and laser assemblies.
Diamond substrate platforms for next-generation electronic, microwave, and optoelectronic device integration.
Optical windows and transmissive components for harsh-environment photonics, spectroscopy, and beam-control systems.
Conductive boron-doped diamond components for electrochemical platforms, specialty electronics, and sensing.
Quantum-grade diamond systems for NV-center research, quantum sensing, and photonic quantum platforms.
Synthetic micron & nano powders for precision polishing, lapping, and slurry workflows.
Diamond moves heat 5× faster than copper and 12× faster than silicon. The most thermally conductive solid material known.
A 5.47 eV bandgap means higher breakdown voltage, lower leakage, and devices that operate at extremes others can't.
Across every axis that matters — thermal, voltage, mobility — diamond outperforms Si, GaN, and SiC by orders of magnitude.
Chemical Vapor Deposition grows diamond atom-by-atom from a hydrocarbon gas mixture under controlled plasma — producing crystals of exceptional purity.
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.
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.
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.
Diamond is inert to nearly all chemicals. Enables unique applications in biosensors, neural interfaces, and harsh-environment optics impossible for other materials.
From 5G infrastructure to quantum computing — diamond unlocks performance impossible with any other material.
High-voltage inverters, EV powertrains, grid-scale converters at extreme power densities.
GaN-on-Diamond RF transistors for 5G base stations, satcom, electronic warfare.
NV-center diamond substrates for quantum sensing, memory, and qubit platforms.
Radiation-hard detectors, high-temperature electronics for hypersonic & space systems.
Diamond heat spreaders for fiber laser pump diodes, CO₂ lasers, optical windows.
SiC/GaN-on-Diamond power modules for next-gen EV chargers and inverters.
Biocompatible coatings for neural implants, biosensors, in-vivo diagnostics.
Diamond abrasives for wafer finishing, ceramics, optical element preparation.
