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 °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 °C. Also, the results showed that the MEH-PPV/PS device has better sensitivity for NO2 gas compared to MEH-PPV/Si.
