Signature of high T(c) above 25 K in high quality superconducting diamond

We have observed zero resistivity above 10 K and an onset of resistivity reduction at 25.2 K in a heavily B-doped diamond film. However, the effective carrier concentration is similar to that of superconducting diamond with a lower T(c). We found that the carrier has a longer mean free path and life...
