Raman scattering in ultraheavily doped silicon

Abstract
Raman spectroscopy has been used to study compositional disorder in ultraheavily doped silicon. The disorder is characterized by line-shape asymmetry of the one-phonon mode and the scattering amplitude of the two-phonon transverse acoustic and transverse optic modes. For implantation doses exceeding the solubility limit, topological disorder also becomes important in determining the phonon correlation length.
