研究開始時の研究の概要 |
The research aims to (1) demonstrate the novel method to reduce the adsorption of oxygen and water molecules on graphene nanoribbon field-effect transistor (GNR-FET) with fluoropolymer GNR (FGNR) as a dielectric and hydrophobic layer, (2) detect multiple volatile organic compounds (VOC) with 1 ppt sensitive and selective detection of individual VOC gas molecules.

研究実績の概要 |
We have fabricated a CVD graphene ribbon (GNR) and Zeolite functionalised graphene-based FET gas sensor. The experimental procedure demonstrates the difference in the resistance of graphene in a particular gas environment. The zeolite functionalised GNR FET showed a sensitivity of 100 ppb towards acetone gas molecules. We have identified that zeolite act as a trapping material to enhance the gas-sensing response. The dependence of this charge transfer on the applied tuning voltage was investigated using the gate modulation technique.

理由
We are carrying out different zeolite materials to capture specific gas adsorption and to prevent the adsorption of oxygen and gas molecules. We also trying to implement our gas sensor device in the real-time application.

今後の研究の推進方策 |
In the next phase of research work, we have planned to functionalize graphene with different zeolites in order to improve the sensitivity and selectivity of gas sensors. We will also find out a better sensor which will be implemented for the real-time health sensor monitoring.
