Problem
Silicon, silicon carbide, and gallium nitride have inherent material limits that constrain the performance of power electronics, thermal management systems, and quantum devices. These materials cannot simultaneously deliver the extreme thermal conductivity, ultra-wide bandgap, and spin coherence properties required for next-generation high-power, high-frequency, and quantum applications, forcing engineers to compromise on efficiency, heat dissipation, and sensitivity.
Solution
Kara Labs grows engineered single-crystal diamond in its own reactorsa material combining the highest known thermal conductivity, a 5.47 eV bandgap, and exceptional carrier mobility. The company performs growth, processing, and characterization entirely in-house, offering substrates with specified crystal orientation, sub-nanometer surface roughness, tailored impurity profiles, and controlled ¹²C isotope fraction for optimal spin coherence. These diamond wafers enable applications ranging from thermal management at the point of heat generation to power electronics with breakdown fields exceeding 10 MV/cmaimanageable in no other semiconductor. Kara Labs also provides characterized research substrates with verified specs to support reproducible work in quantum sensing, photonics, and quantum networks.
Target Audience
Primary customers are R&D teams in semiconductor power electronics, quantum sensing and computing, photonics, and thermal management, along with research institutions needing characterized diamond substrates for reproducible experiments.
