摘要：

In this work, novel MEH-PPV/Si and MEH-PPV/PS heterojunction gas sensors were fabricated and characterized. The sensitivity and response time were measured at different operating temperatures (30, 100, 200 degrees C). The results showed that the maximum sensitivity of the MEH-PPV/Si device to NO2 gas is 16% at room temperature, while the maximum value of 74% was measured at 200 degrees C. Also, the results showed that the MEH-PPV/PS device has better sensitivity for NO2 gas compared to MEH-PPV/Si.
