The Science Behind Diamond Semiconductors
Diamond is the ultimate semiconductor material — its physical properties exceed every known alternative across thermal, electronic, and mechanical domains.
Why Diamond Outperforms Everything
-
Unmatched Thermal Performance — 2,200 W/m·K — over 10x better than SiC and 5x better than copper.
-
Wide Bandgap Advantage — 5.5 eV bandgap enables devices at voltages and temperatures impossible for silicon or GaN.
-
Surging Market Demand — CVD diamond market projected to grow from ~$500M in 2025 to over $1.5B by 2033.
