摘要：

The electrical properties of sputtered thin-films of CuBr are measured using gold or copper electrodes and in presence of ammonia. The I-V characteristics are strongly dependent on the choice of the electrode metal: an ohmic response is observed with copper electrodes, which act reversibly for ion exchange, but exponential dependencies are measured with blocking gold contacts. An increase of the film resistance is observed in presence of ammonia. the response time is very short and the signal is reversible. (C) 1999 Elsevier Science Limited. All rights reserved.
