The purpose of this study is to investigate the potential of nanostructured Au-TiO2 particles in replacing traditional materials for gas sensing applications. The researchers used a pulsed laser deposition technique to prepare and analyze Au-TiO2 nanoparticles on a Porous Silicon substrate. The findings suggest that the Au-TiO2 nanoparticles play a significant role in developing electrical properties and enhancing sensitivity to H2S and NO2 gases.
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.
