Abstract:The modelling of a top-gated and bottom-gated Graphene-based Nano Ribbon Field Effect transistor (GNRFET) for sensing of N 2 O and O 2 gases is performed using Sentaurus TCAD and VASP by diffusing the gases over the surface of the Graphene Nano Ribbon (GNR) layer. The Sentaurus model corresponds to that of a doped GNR placed over the gate separated by a thin layer of insulator. From a VASP modelling of a zigzag GNR (ZGNR) doped with Gallium and Phosphorus, it has been observed that the density of states functi… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
