Abstract
In this paper, a plasmonic sensor utilizing bimetallic layer of Ag/Au with ۲D material WS۲, and Ti۳C۲Tx MXene is studied. The proposed SPR sensor is a free space structure using the Kretschmann configuration to stimulate surface plasmons (SPs). The finite-difference time-domain method is used to analyze the optical behavior of the proposed SPR sensor. The results show the proposed SPR sensor has the maximum sensitivity of ۲۴۲ deg/RIU with ۳۵ nm of Ag, ۱۵ nm of Au with monolayer of ۲D material WS۲ and one layer of Ti۳C۲Tx MXene. We predict that the proposed structure can be used for biosensing and chemical sensing applications.
Keywords: Sensitivity, surface plasmon resonance, refractive index, sensor, Ti۳C۲Tx MXene.
