A procedure for depositing and patterning thin polypyrrole films is described. Geometrical resolution tests are presented showing that lines with submicrometric width can be produced by means of this technique. Noise measurements performed on balanced polypyrrole thin-film microbridges are presented. The measurements are aimed to study the effects of exposure to gaseous species on the spectral density of the resistance fluctuations. The use of balanced structures permits the effects of d.c. voltage transients and drift on the measured power spectra to be reduced.

Abstract
A procedure for depositing and patterning thin polypyrrole films is described. Geometrical resolution tests are presented showing that lines with submicrometric width can be produced by means of this technique. Noise measurements performed on balanced polypyrrole thin-film microbridges are presented. The measurements are aimed to study the effects of exposure to gaseous species on the spectral density of the resistance fluctuations. The use of balanced structures permits the effects of d.c. voltage transients and drift on the measured power spectra to be reduced.File in questo prodotto:
