| Outline of Final Research Achievements |
Silicon (Si) inks for forming porous Si films were produced by modifying the Si ink particle surface with various organic molecules. The obtained films were semiconductive, and showed gas sensing properties: the electrical conductivity changed during exposure to oxidizing gas (oxygen and carbon dioxide) or reducing gas (carbon monoxide). Besides, the films showed photoconductivity peculiar to Si nanostructures: The conductivity largely increased during exposure to light the photon energy of which was higher than twice the bandgap energy.
