Study of Characteristics of the Sensor Detecting of Low Concentration of Ammonia
In this work, the morphology of Fe 2 O 3 :ZnO (60 : 40 mol %) film and gas sensing characteristics to ammonia vapors at different operating temperatures were investigated. The SEM investigation of the surface of the sensitive film of Fe 2 O 3 :ZnO showed that the grain size in the film was about 50 ...
