Various nanostructures can be developed through oxygen-controlled sputter, transitioning from a triangular configuration to a grain with a smooth surface. In the current study, the P-N junction of double-layer CuO/SnO was generated for gas sensing application, where the nanostructure is varied by modifying argon to oxygen concentration in the sputter chamber. NO gas is tested for triangular CuO/SnO sensor application, and sensing results revealed a sensor response of 10.6 (R/R) at 0.2 ppm and a response of 57.2 (R/R) at 1 ppm. In order to evaluate the anti-interference performance, the sensing performance was tested using HS, NH, CO, and H to determine the sensor's anti-interference performance with good reproducibility.

用于 NO2 检测的氧控 CuO/SnO2 传感器的合成和表征


通过氧控制溅射可以形成各种纳米结构，从三角形结构转变为具有光滑表面的颗粒。在当前的研究中，双层 CuO/SnO 的 PN 结用于气体传感应用，其中纳米结构通过改变溅射室中的氩气和氧气浓度来改变。针对三角形 CuO/SnO 传感器应用测试了 NO 气体，传感结果显示，传感器在 0.2 ppm 处的响应为 10.6 (R/R)，在 1 ppm 处的响应为 57.2 (R/R)。为了评估传感器的抗干扰性能，使用H2S、NH、CO和H对传感性能进行测试，以确定传感器的抗干扰性能，具有良好的重复性。
