ABSTRACT:
A method of manufacturing ultrafine particles of a compound composed of at least two elements on the surface of a substrate made of at least one material selected from the group including an organic material and an inorganic material, the method including: depositing a first element onto a surface of the substrate to provide a layer of particles of the first element; depositing successively at least one additional element onto the layer of the first element on the surface of the substrate to provide respective layers of particles of the at least one additional element, the successive depositions taking place at respective deposition rate ranges which are effective for forming a compound by spontaneously alloying the first element and the at least one additional element over a time period effective to provide a preselected area density; and reacting the layers of particles on the substrate at a reaction temperature ranging from below 32.degree. C. to -173.degree. C., and under a vacuum ranging from 10.sup.-11 to 10.sup.-1 Torr to spontaneously alloy the first element and the at least one additional element.
