Abstract :
This work deals with a special class of functional ceramic materials, namely gas-sensitive layers made of wide bandgap oxide semiconductors. At present, SnO/sub 2/ semiconductor gas sensors are most frequently produced, because no material capable of competing with tin oxide in performance has been development. Rather than continuing with the search for a new material, a recent trend indicates more detailed study of SnO/sub 2/ to increase its performance.
