  • Abstract
    In the present work, we report the performance of grapheme-based gas sensors. Monolayer quality graphene was synthesized using thermal chemical vapor deposition. Graphene was characterized using Raman spectroscopy and Transmission electron microscopy. In addition, Hall Effect experiments were conducted to study the electronic properties of graphene layers. These graphene layers were tested to sense NO2, NH3, and Ethanol at room temperature. The responses of the grapheme based gas sensor are highly reproducible.
