摘要：

The microstructure, electrical properties, aging, and electrolytic decomposition of sputtered CuBr films. are described and discussed with respect to the defect chemistry of this mixed Cu+ ion-electron hole conductor. Ammonia gas adsorption increases the electrical resistance of the films. This effect can be used to design a new selective, sensitive, fast, and reversible ammonia gas sensor.
