H, in air can be detected with sensors based on semiconductor oxides. A new technique for growing a hydrogen sensor based on SnO,(Bi,O,) thin films is presented here. The thin films have a thickness of 200-250 nm and the metals are in the atomic ratio Bi/Sn.= (3-S) at.%](97-95) at.%. The two metals
