Article Synopsis
- Organic field-effect transistors (OFETs) are gaining popularity for detecting volatile organic compounds (VOCs) due to their ability to provide versatile, multiparameter measurements and signal amplification.
- However, false readings can undermine their effectiveness and lead to output errors during gas-sensing.
- This study clarifies how VOC adsorption affects OFET performance, highlighting the source-drain current as the key parameter for high responsivity and establishing guidelines for improved measurements in gas-sensing applications.
Article Synopsis
- A source-drain electrode using a MoO interfacial modification layer (IML) can improve organic thin-film transistors (OTFTs) but risks device instability due to MoO diffusion into organic materials.
- To mitigate this issue, a multilayered interface contact (MIC) design is proposed that includes an organic buffer layer (OBL) to prevent MoO diffusion while maintaining low contact resistance.
- The study analyzes the effects of various organic compounds as buffer layers and establishes key parameters, like the Fick coefficient, to guide future material selection for more stable OTFTs.
