Diamond Foundry says its diamond-based transistors, developed with Stanford University, switch 50 times faster than silicon devices. The company also says they match the subthreshold-swing performance of state-of-the-art 3 nm silicon transistors.

The approach uses surface transfer doping to create charge carriers without adding dopant atoms to the diamond’s bulk. That makes this a concrete semiconductor development, not just a pitch for a shinier material. The figures are Diamond Foundry’s claims; the page gives no testing detail to judge the comparison. Still, diamond’s properties make it an intriguing candidate for future electronics.

Discuss: Would you back a new material on headline performance claims, or wait for fuller evidence from independent testing?
