Functional Nanocomposites Formation by Electrochemical Deposition of Metals and Semiconductors into Porous Silicon

摘要

The paper concerns the study of formation of nanocomposites by electrochemical deposition of metals and semiconductors into the porous silicon. Ni and ZnO were used as experimental materials for deposition. The influence of deposition process parameters and structure of initial porous silicon substrates on morphology and composition of formed metal or semiconductor nanostructures are studied. Obtained nanocomposites demonstrated high filling factor and uniformity. Porous silicon/Ni nanocomposites showed strong magnetic anisotropy. Porous silicon/ZnO nanocomposites after thermal annealing had intensive photoluminescence in the visible range. Applications of obtained nanocomposites in the magnetic and optoelectronic devices discussed as well.
