摘要：

CuO/SnO2 heterostructures as well as SnO2(CuO) polycrystalline films have been studied for H2S sensing. Gas sensing properties of these materials have been compared in conditions: 25-300 ppm H2S in N-2 at 100-250 degrees C. A shorter response time of the heterostructures as compared to that of the SnO2(CuO) films has been found. It is suggested that the improvement of dynamic sensor properties of SnO2/CuO heterostructures is caused by the localization of electrical barrier between CuO and SnO2 layers.
