摘要: Abstract CuO/SnO2 heterostructures as well SnO2(CuO) polycrystalline films have been studied for H2S sensing. Gas sensing properties of these materials compared in conditions: 25–300 ppm N2 at 100–250°C. A shorter response time the to that has found. It is suggested improvement dynamic sensor SnO2/CuO caused by localization electrical barrier between CuO and SnO2 layers.
