Plasmon-Based Gas Detection with Graphene Ribbons

ORAL

Abstract

Gas detection has impact across a wide range of disciplines with established markets in variety of industries, including healthcare, security, environmental, semiconductor, etc. Motivated by the recent experiments, which exploit plasmons in graphene to identify gas molecules, here, we inspect a prototype setup, where an array of graphene ribbons enables plasmon-based gas detection via trapping the molecules atop graphene surface. We explore the main trapping mechanisms in the setup, and discuss how these allow for plasmon-based detection with enhanced sensitivity.
