- Abstract
- The SnO2 nanowire networks were grown on a laser-scribed Al2O3 substrate containing 16 sensor elements with Au electrodes and Pt heaters via a single step vapor phase reaction, and their gas sensing characteristics were studied. The sensor showed a high response to 5 ppm NO2 (R-g/R-a = 1909, R-g: resistance in gas, R-a: resistance in air) at the sensor temperature of 141 degrees C and high and selective responses to 100 ppm C2H5OH (R-a/R-g= 301.8-326.4) at 240 and 296 degrees C. which demonstrated that high performance SnO2 nanowire network gas sensors can be fabricated on a large scale through a facile and cost-effective route.
