| 摘 要： | ＺｎＯ压敏陶瓷在工作电压长期作用下，会产生电流蠕变现象，使Ｓｃｈｏｔｋｙ势垒不稳定．用正电子湮没技术（ＰＡＴ）证实：ＺｎＯ在适当温度下的氧化热处理，使氧离子Ｏ－或Ｏ２－吸附于晶界层内并有利于提高ＺｎＯ性能稳定性

| Abstract: | Voltage sensitive ZnO ceramic is shown to produce current creep when voltage is applied for a long period, which results in the instability of Schottky barrier. The PAT studies prove that if ZnO is treated by oxidation at a suitable temperature, oxygen ion O - or O 2- can be absorbed into intergranular boundaries, which improves the ceramic property stability. |
