Silicon Nano Structures for Hydrogen Detection

Muna S. M. Jawad

Abstract :

Silicon nanostructures layer was formed by electrochemical anodization on p-type silicon surface. TiO and ZnO[Al] thin films were deposited onto silicon nanostructures surface by electron-beam evaporation. A Pt catalytic layer and Au electrical contacts for further electrical measurements were deposited by thermal evaporation. Changes in sensitivity versus time of obtained structures were examined for different concentrations of hydrogen gas and propane–butane mixture. High sensitivity and selectivity to hydrogen gas was detected. All measurements were carried out at 40 °C
