P1.0.4 Enhanced Room Temperature Response of SnO2 Thin Film Sensor Loaded with Pd Catalyst Clusters Under UV Radiation for Methane

Divya Haridas, Keshav Mahavidyalaya & Vinay Gupta
Room temperature response characteristics of SnO2 thin film sensors loaded with palladium catalyst clusters of varying thickness are investigated for methane under the exposure of ultraviolet radiation. The SnO2-Pd cluster sensor structures have been prepared using rf sputtering. Combined effect of UV radiation exposure (wavelength=365 nm) and presence of Pd catalyst clusters (10 nm thick) on SnO2 thin film sensor surface is seen to lead to an enhanced sensing response (252.3) for the detection of...
