Study effect of magnetic field on Au-TiO2 nanoparticles ablated on silicon nanostructures for gas sensors

The purpose of this study is to explore if nanostructured Au-TiO2 particles can replace traditional, bulkier materials in gas sensing applications. Then use a Nd-YAG laser with a wavelength of 1064 nm, number of shot 500 pulse, and 500 mJ, 660 mJ, and 820 mJ laser ablated energy, the pulsed laser deposition technique has been widely used to prepare and characterize Au-TiO2 nanoparticles on Porous Silicon substrate produced on n-type Silicon wafer. By using of drop casting method, the Au-TiO2 NPs have deposited on porous silicon (PS) layer with 15 drops of each specimen. The morphology of PS layer, Au:TiO2 NPs and Au-TiO2 NPs/PS specimens were reviewed using scanning electron microscopy, XRD pattern analysis, and transmission electron microscopy. We found that the Au:TiO2 NPs play important role to develop electrical properties and sensitivity to H2S and NO2.

Automated summary
