本文在表面基模型基础上,借用半导体物理中复合/产生概念,提出表面基/复合中心模型,并研究了含两种类型表面基的Si3N4绝缘体及其两种表面基(硅醇基和胺基)的比率对Si3N4栅pH-ISFET敏感性能和稳定性的影响,其结果与实验结果相符。对改善pH-ISFET传感器的敏感特性具有实际指导意义。
Based on the site-binding model
being the recombination/generation concept of semiconductor physics for reference
a surface-site/recombination center model for the process of H+-ion dissociation-association in electrolyte-insulator(E-I) interface is presented.The effect of the Si3N4 insulator which contains two types of surface-sites and the ratio of silanol site to amine site on sensitive characteristic and stability of Si3N4-gate pH-ISFET is also discussed
and the results correspond with experimental results.It is useful in improving sensitive characteristic of pHISFET sensors.
