Abstract
We demonstrated the silicon nanowires structure sensing response by measuring the change in electrical conductance upon NH3 gas exposure. Measurements were taken for SiNW and TiO2 decorated SiNW samples at very low concentrations of ammonia gas starting from 1 ppm up to 11.8 ppm. Results showed an increase in sensitivity and lower response time to ammonia gas in presence of 50% humidity.
