Abstract
A method for the galvanic deposition of iron-group metals onto porous silicon (por-Si) substrates has been developed. The morphology and phase composition of por-Si nanocomposites containing galvanically deposited particles of Fe, Co, and their mixtures have been studied by scanning electron microscopy (SEM), ultrasoft X-ray emission spectroscopy (USXES), and X-ray absorption near-edge structure spectroscopy (XANES) techniques. It is established that iron uniformly covers the surface of porous silicon, whereas cobalt penetrates deep into pores in the form of nanoparticles. During the galvanic codeposition of both metals from a mixed solution of their salts, cobalt favors the penetration of iron in depth of the pores.
