Diamond Chips Move Closer as Scientists Decode Superconducting Granularity (opens in new tab)

Researchers found that critically boron-doped diamond films can develop intrinsic electronic granularity, producing three tunable superconducting transport phases despite structural uniformity. The findings show how temperature, magnetic field, and current direction can reshape anisotropic superconducting behavior in diamond, with implications for future quantum-on-chip platforms.
