Abstract
Abstract In this work we propose that the observed superconductivity in hole-doped diamond is due to an electron–phonon mechanism and substantiate the idea by first-principles full potential LMTO linear-response calculations. Our calculations, based on the virtual crystal approximation (VCA), show that the holes at the top of the zone-centered, degenerate σ bonding valence band couple strongly to the optical bond-stretching modes, in a very similar way as found in MgB 2 . We discuss the main similarities and differences between the two systems, as well as the doping dependence of T c in diamond and the possibility of observing superconductivity in Si and Ge.
