The designed NWFET for gas sensing is observed to have a higher ratio of I ON to I OFF than 10 9 , lower DIBL and better gate controlling due to a higher surface to volume ratio. The gas-sensing performance analysis has been done for three different catalysts, iridium (Ir), ruthenium (Ru), and palladium (Pd), by gradually increasing the work function by a difference of 50meV. The device showed higher OFF current sensitivity compared to ON current sensitivity. The power consumption and threshold voltage are observed to be least for palladium catalytic gate electrodes making palladium the most favorable catalytic for ammonia gas for the designed gas sensor.
