Fm. Devienne et al., SYNTHESIS OF SILICON-OXYGEN DERIVATIVES IN QUASI-INTERSTELLAR CONDITIONS, COMPTES RENDUS DE L ACADEMIE DES SCIENCES SERIE II FASCICULE C-CHIMIE, 1(7), 1998, pp. 425-429
Bombardment of a silicon target in high vacuum with a molecular beam o
f krypton in the presence of thermal oxygen atoms produces ions, which
give a primary spectrum. The individual peaks of this spectrum are ex
tracted and dissociated in a collision cell. Mass analysis of the ions
and of their fragments leads to the identification of silicon-oxygen
derivatives, the composition of which is established by using the pres
ence of the three naturally occurring isotopes of silicon. The derivat
ives formed represent a series of silicon suboxides ranging from SiO t
o Si10O3.SiO2 is weak, as expected from its normal existence as a thre
e-dimensional lattice, nor as isolated molecules. (C) Academie des sci
