Displacements of Sb atoms in supersaturated Sb-doped Si layer formed by molecular beam epitaxy growth Academic Article uri icon

abstract

  • Rutherford backscattering channeling measurements with angular scans have been carried out on 〈 100 〉 Sb-doped Si superlattice structures formed by molecular beam epitaxy growth. Three different crystallographic axes 〈 100 〉, 〈 111 〉, and 〈 110 〉 have been explored. We have observed Sb displacements from their substitutional sites with displacement amplitudes of 0.22 Å in as-grown samples. The displacements increase with increasing post-growth annealing temperatures, associated with formation of nanometer size Sb precipitates. © 2007 American Institute of Physics.
