| 摘 要： | n p型半导体气体传感器是基于气体传感器互补增强和互补反馈原理的一种新结构半导体气体传感器。该种传感器是由两种传导类型不同的敏感体A和B构成,A是n型半导体材料,B是p型半导体材料。理论分析表明,敏感体A和B的选择必须满足一定的原则,才能实现该种传感器的高性能。 |
| 关 键 词： | 气体传感器 n p组合结构 互补增强 互补反馈 灵敏度 热稳定性 选材原则 |

| Abstract: | n p structure semiconductor gas sensor based on the compensation-multiplication and compensation-feedback principle is a new type gas sensor. The sensor is composed of two sensitive materials: A and B, whose conductive types are not the same. Material A is a n-type, and B is a p-type. The results analyzed from the theoretical viewpoint showed that the n p combined structure semiconductor gas sensor has better properties when the materials A and B satisfied certain conditions. The conditions to achieve these characteristics of the n p combined structure semiconductor gas sensor are presented. |
| Keywords: | gas sensor N p Combined Structure compensation-multiplication compensation-feedback sensitivity thermal stability choosing sensitive material principle |
