【摘要】 讨论了基于气敏元件互补反馈和互补增强原理的新型半导体n+p结构气敏元件.理论分析表明,该新型气敏元件具有高的选择性,同时还具有好的热稳定性和高的灵敏度.通过实验,获得了性能较好的n+p结构酒敏元件.
【Abstract】 A new type semiconductor n + p structure gas sensor is put forth, which adopts the compensation -feedback and compensation - multiplication principle and sensor` s structure of achieving principle. The results investigated from theortical viewpoint show that the n + p combined structure gas sensor has high selectivity, better thermostability and high sensitivity. The perfect n + p combined structure alcohol gas sensor is fabricated and tested.
