We investigate the properties of the semi-conducting polymer polypyrrol (PPy) in parallel, tubular pores of monolithic micro- (pore diameter D < 2nm)-, meso- (2 < D < 20nm) and macroporous (D > 50 nm) silicon (PSi). On the one hand PPy offers the opportunity to modify the electrical conductivity of the PSi, while sensoric and actoric applications for the PPy/PSi hybrid system are possible as well. We investigate the electrochemical polymerisation process of PPy in PSi [1] with regards to the orientation of the molecules in the pores and the role of the pore surfaces.
