This project focuses on investigations of Polypyrol (PPy) inside tubular pores in a micro-, meso-, and macro-porous Silicon (PSi). PPy offers the possibility to modify the electrical conductivity of PSi in a controlled way. It furthermore opens up sensoric and actoric applications for the PPy/PSi hybrid system. The experiments with the 1D system will be complemented by investigations in the planar 2D geometry. This combined approach permits to establish PPy/PSi as a multiscale hybrid model system within the SFB 986, and at the same time it opens up application-oriented developments.
