Hybrid Structure–Based SPR Sensor for Chemical Sensing with Enhanced Sensitivity
In this paper, we have proposed a new multilayer structure and investigated its performance as a chemical sensor utilizing surface plasmon resonance. Our proposed design consists of a black phosphorus layer sandwiched between a metal layer and a graphene layer, blue phosphorene/MoS2 heterostructure layers placed over it, and the sensing layer containing the analyte placed on top. A CaF2 prism in the Kretschmann configuration is employed to excite surface plasmon resonance (SPR), and the angle interrogation method is used for analysis. Sellmeier equations calculate the reflectivity and other parameters of the multilayer design. We also study the effect of the combination of BP and metal interlayer. Analysis of the proposed design shows significantly improved sensitivity compared to recent SPR-based sensors. In this paper, the sensitivity of 466°/RIU is obtained with silver metal, BP, graphene, and BlueP/MoS2 layers SPR sensor.
期刊介绍：
Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons.
Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
