The OTFTs have become an attractive research field of the electronic nose applications, which develop low cost portable sensing systems by using organic semiconductor. In this paper. we fabricated flexible polymer OTFTs by using solution process. And also, we observed gas sensing properties of fabricated flexible OTFTs with ammonia (NH3) gas. The transfer curves of fabricated flexible polymer OTFTs that were continuously measured under exposure of NH3 gas. In the p-type semiconductor, the measured drain current was decreased, as exposure in the gas was increased. And also, we observed that the channel resistance was linearly changed. Therefore, the fabricated OTFTs are possible for gas sensor device. |
