Superconducting and Normal State Properties of Heavily Hole-Doped Diamond
arXiv:cond-mat/0409624 · doi:10.1103/PhysRevB.71.060502
Abstract
We report measurements of the specific heat, Hall effect, upper critical field and resistivity on bulk, B-doped diamond prepared by reacting amorphous B and graphite under high-pressure/high-temperature conditions. These experiments establish unambiguous evidence for bulk superconductivity and provide a consistent set of materials parameters that favor a conventional, weak coupling electron-phonon interpretation of the superconducting mechanism at high hole doping.
