Zusammenfassung:Polypyrrole has been electrodeposited in the interior of the pores that form the porous silicon structure, and a very significant increase of the electrical conductivity of the samples has been observed. Micro-Raman spectroscopy experiments have allowed us to measure the amount of polymer as a function of the distance from the outer porous silicon surface. The degree of filling by the polymer has been found to be highly dependent on the electropolymerization conditions, particularly the current density applied.
