In this process, a complicated and individual alignment process could be avoided and a number of devices can be fabricated in one step in a wafer scale. The gas-sensing characteristics of the developed sensor were significantly better when compared to those of other types of NO2 sensors reported in the literature. When the concentration of NO2 was 5 ppm, the sensitivity was higher than 150. Especially, the reaction time of 8-14 s was noticeably fast, which is attributed to the microtrench structure beneath the nanowires.
