| 摘 要： | 用化学共沉淀法，经热处理制得Ｚｎ＿（１－ｙ）Ａｌ＿ｙＯ系敏感材料。实验发现，在ｙ＜０．０８区间内，材料的电阻降低幅度较大，当ｙ＞０．０８时，阻值开始随ｙ值增大而上升。ＸＲＤ分析表明Ｚｎ＿（１－ｙ）Ａｌ＿ｙＯ（Ｏ＜ｙ＜０．１）是固溶体，此体系中存在缺陷平衡，并探讨其导电机制。

| Abstract: | This paper reports the investigation on relationship of conductive mechanism with solid solubilityin Zn_(1-y)Al_yO n-type semiconductor system prepared by co-precipitation method.It is found that the resistance of the system remarkably decreased while y<0.08,but it slowlyincreased as the range of y value was from 0.08 to 0.30 Zn_(1-y)Al_yO system with 0
