Abstract

Acetylene and oxygen adsorption on disordered and ordered silicon crystal surfaces of (111) orientation were studied by low-energy electron loss spectroscopy (ELS). There are marked structure-dependent differences in the ELS spectra in the presence of these adsorbates. A model for the acetylene molecule orientation on the silicon (111) ordered surface is proposed to explain the experimental results. ELS data suggest that the electrons in the silicon-oxygen chemisorption bond are more tightly bound on the disordered than on the silicon (111) surface with a (7 X 7) surface structure.
