Query: Superconductivity in doped cubic silicon: an ab initio study   We study within a first-principle approach the band structure, vibrational
modes and electron-phonon coupling in boron, aluminum and phosphorus doped
silicon in the diamond phase. Our results provide evidences that the recently
discovered superconducting transition in boron doped cubic silicon can be
explained within a standard phonon-mediated mechanism. The importance of
lattice compression and dopant related stretching modes are emphasized. We find
that T$_C$ can be increased by one order of magnitude by adopting aluminum
doping instead of boron.
