摘　　要：提出了SiC-SBD气体传感器器件分析模型,利用当前流行的MATLAB强大的计算编程功能,模拟了SiC-SBD气体传感器的电流-电压特性,结果与实验数据吻合很好,较好地解释了Pd-SiC肖特基二极管比较灵敏的原因,并根据模拟结果提出了提高传感器灵敏度的方法。An analysis device model of SiC-SBD gas sensors was developed. The I-V characteristics of SiC-SBD gas sensors were simulated by the popular and powerful MATLAB. The results exactly agree with the experiment results. In addition, it explains why Pd-SiC Schottky diodes are more sensitive and find a way to improve the sensitivity of gas sensors. Some approaches to increase sensibility are given based on the model.
