A study of the neutral undistorted vacancy in silicon

Lindefelt, Ulf (1978) In Journal of Physics C: Solid State Physics 11(17). p.3651-3651
Abstract
Within the local energy independent pseudopotential theory, a convergent supercell calculation of the position of the discrete impurity level produced by the neutral undistorted vacancy in silicon has been performed. Translational symmetry was reintroduced by placing the impurities on a Bravais lattice. The author made calculations with unit cells containing up to 2662 atoms plus vacancy. A deep level in the lower part of the fundamental band gap is found, lying 0.18 eV above the top of the valence bands. The results also indicate that the localised impurity wavefunction decreases rather slowly and extends to 30 Å.(35 refs)
