RESUMEN

The SnO2 thin film CO gas sensors have been fabricated on silicon nanostructured surface made using a femtosecond pulsed laser irradiation. The measurement shows a significant response to the CO gas at room temperature. While a SnO2 sensor fabricated on a flat surface shows no response when CO gas exists at room temperature. The high area/volume ratio and sharp structures of the nanospikes enhance the sensitivity of SnO2 at room temperature.
