Why Diamond is the Semiconductor Material of the Next Decade

Silicon dominated computing for 60 years. SiC and GaN are extending the roadmap into power electronics. But as power densities climb past 10 kW/cm² and operating temperatures approach 300°C, a harder material truth is emerging: only diamond can bridge the gap between where semiconductors are today and where AI, quantum, and electrification need them to be.

The Thermal Crisis in AI Infrastructure — And Why Diamond Solves It

NVIDIA's GB200 NVL72 dissipates 120 kW per rack. Liquid cooling alone isn't enough. This is why diamond heat spreaders are becoming a standard thermal component in next-generation AI clusters.

Beyond SiC: Why Diamond is the Long-Term Power Substrate

SiC has been the power electronics substrate story of the 2020s. But at power densities above 10 kW/cm², diamond's superior thermal and breakdown properties are no longer academic — they're necessary.
