Popis: n-type semiconducting ZnO film with Ag electrode changes into Ag ionic conductor by heating in air. The dominating conduction carrier in such a film is Ag ion in air, and it changes into electron by the introduction of air-containing reducing gas or oxygen free atmosphere. The Ag ionic conductance is high in air and decreases by introduction of air-containing reducing gas or oxygen-free atmosphere. dc polarization and precipitation of silver metal on cathode indicate the Ag conduction depending on atmosphere. The effect of the atmosphere on silver penetration into ZnO film has been measured by using SIMS.
