The technique of obtaining Ag/Por-Si composite material with homogeneously distributed silver nanoparticles over the surface of porous silicon by one cycle of electrochemical treatment of single-crystalline silicon. The effect is achieved by using an electrolyte to produce porous silicon with a special composition containing silver ions. During the electrochemical anode treatment of single-crystalline silicon in Ag-containing electrolyte a layer of porous silicon and silver islets are formed on the sample surface simultaneously. It is shown that the controlling the conditions of electrochemical processing provide an opportunity to form homogeneously distributed on the surface silver nanoparticles with a narrow-size distribution.
