dc.description.abstract | We introduced a selective and self-heated CO gas sensor based on Au-decorated WS2 nanosheets. Au nanoparticles (NPs) were decorated on WS2 NSs using UV irradiation technique at different irradiation times (1, 15 and 30 s). SiO₂ grown on Si was used as substrates and the gas sensors with top electrode configuration were fabricated. Gas sensors were able to work under self-heating mode with an applied voltage of 2 V for selective CO sensing. The results of CO gas sensing demonstrated the promising effects of Au for the enhanced response and selectivity towards CO gas. Also, the low-voltage operation at room temperature resulted in low-power consumption. This study demonstrates realization of selective CO gas sensor using a facile approach along with low power consumption. | - |
