通过在400 ℃下热氧化Cu箔来生长CuO纳米线（NW），并且通过沉积含有CuO纳米线的溶液来制造气体传感器。在300-370摄氏度时，传感器电阻在暴露于30-100 ppm CO时增加。这可以通过p型氧化物半导体的气体传感特性来解释。相比之下，传感器显示出两种相反的NO2传感行为;在暴露于30-100 ppm NO2时，电阻降低。但一旦接触到
CuO nanowires (NWs) were grown by the thermal oxidation of Cu foil at 400 degrees C and gas sensors were fabricated by the deposition of a solution containing the CuO NWs. At 300-370 degrees C, the sensor resistance increased upon exposure to 30-100 ppm CO. This has been explained by the gas sensing characteristics of the p-type oxide semiconductor. In contrast, the sensor showed two opposite NO2 sensing behaviors; the resistance decreased upon exposure to 30-100 ppm NO2. but increased upon contact with
