Abstract
Polypyrrole has been electrodeposited in the interior of the pores that for m the porous silicon structure, and a very significant increase of the elec trical conductivity of the samples has been observed. Micro-Raman spectrosc opy experiments have allowed us to measure the amount of polymer as a funct ion of the distance from the outer porous silicon surface. The degree of fi lling by the polymer has been found to be highly dependent on the electropo lymerization conditions, particularly the current density applied. (C) 1999 Elsevier Science S.A.
