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 sigma bonding valence band couple strongly to
the optical bond-stretching modes, in a very similar way as found in
MgB2. 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. (c) 2005
