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.
