| Popis: | The alloying behaviour of antimony molecules Sb4 into nanometre size indium clusters deposited on amorphous carbon has been studied by transmission electron microscopy and selected area electron diffraction for morphological and structural characterizations, and by energy dispersive X-ray spectroscopy for analysis of composition. First, large indium clusters containing about 1700 atoms (mean diameter = 4.4 nm) formed by the gas aggregation technique in a thermal source are deposited on amorphous carbon. Nucleation and growth mechanisms lead to the formation of indium particles randomly dispersed on the substrate. Then antimony molecules evaporated at various thicknesses are deposited on to the indium aggregates. These two successive depositions have been performed at room temperature. A dissolution of antimony atoms into the indium particles takes place and InSb compound is successfully formed. InSb particles as produced have the zinc-blende structure (sphalerite type) which is the structure of t... |
