Plasmonic Gas Sensor based on Graphene Sheet and Trapezoidal Nanotrenches on Silver Substrate

Morteza Maleki and Somayeh Yousefi

Not Accessible

Your library or personal account may give you access

Abstract

Trenches introduced in a two-dimensional grating, filled and covered with Si3N4. The graphene sheet leads to perfect absorption at 672 nm where the surface plasmon mode shows a sensitivity of 440 nm/RIU in gas-sensing applications.
