✦ Synopsis


The influence of doping with acceptor atoms boron and aluminum and donor atoms nitrogen and phosphorus on silicon clusters as a model for semiconductors is investigated by semiempirical calculations with the MO method SINDO 1. The series XSi.,, XSi16, XS& and XSi3, is compared for X =Si, B, Al, N, Pas the central atom on the restricted open-shell Hartree-Fock level. The trends in geometries, ionization potentials, binding energies per atom and average atomic valence numben are presented. From these results, it is concluded that the doping of free silicon clusters does not reflect doping in solid silicon. The chemical properties of these clusters are mainly determined by the dangling bonds at the surface, rather than by the central doping atom.

Using full-muffin-tin-orbital molecular-dynamics (FP-LMTO-MD) method, we have investigated the effect of aluminum heteroatoms on the geometric structures and bond characteristics of Si n (n ¼ 5-10) clusters in detail. It is found that the geometric framework of the ground state structures for Si n (
