Jamieson Replacing enough carbon with boron turns diamond into a superconductor, making it even more interesting for applications in electronics, quantum computing, and photon detection. Currently the best samples only superconduct below 10 K, but theory predicts that this threshold could be pushed much higher. Taking an unconventional approach, the authors systematically compensate charge carriers in a single sample using high-energy ion implantation, revealing a strong link between hole concentration and superconductivity. The demonstrated ability to directly alter diamond’s superconducting properties through ion implantation and annealing is promising for device engineering. [Phys. Rev.
