Abstract

We have examined chemical reactions of small silicon cluster ions Si n+ for n = 7-16 with polar organic molecules M (M = CH3CN, CD3OD, C2H5CN, and C 2H5OH). The intensities of the adsorption products Si nMm+ for m = 1 and 2 were investigated as a function of n. We found for all polar molecules that the relative intensity of SinM+ to the unreacted Sin+ is smaller for n = 11, 13, and 14, that is, the adsorption reactivity is smaller for these n than others. It was also commonly observed that the SigM 2+ ion are more intense than neighboring n. We discussed the relationship of the reactivity with the geometrical structures and the stabilities of the bare Sin+ ions and adsorbed Si n(CH3CN)m+ ions, from theoretical calculations based on density functional theory.
