Abstract :
Binary clusters SinCm are produced in a laser vaporization source from SixC1−x mixed targets. Different composition regimes are investigated by abundance and photoinduced dissociation mass spectroscopy. In the case of stoichiometric silicon-carbide clusters (x = 0.5), no clear magic size is detected but rather the marked effects of a lower binding energy of silicon as compared to carbon atoms. The structural changes induced by the presence of foreign atoms are discussed in the case of carbon-rich clusters (x ⪡ 1) for which the formation of heterofullerenes is observed.
