Sensitivity-Enhanced Surface Plasmon Resonance Sensor Based on Zinc Oxide and BlueP-MoS2 Heterostructure
A novel design of a surface plasmon resonance (SPR) sensor based on the heterostructure of 2D nanomaterials, viz. blue phosphorus (BlueP) and molybdenum disulfide (MoS2), coupled with an adhesive layer of zinc oxide (ZnO) is presented here to enable significant plasmonic performance enhancement. The five-layer SPR system based on the Kretschmann configuration consists of ZnO sandwiched between a BK7 glass prism and gold (Au) layer, a BlueP-MoS2 heterostructure, and a sensing medium. The numerical analysis of the proposed sensor is carried out using the transfer matrix method and the sensor performance parameters; sensitivity, full width at half maximum (FWHM), and quality factor (QF) are studied at an operating wavelength of 633 nm for refractive index change in the range 1.33–1.335 RIU. The thicknesses of the Au, ZnO, and BlueP-MoS2 heterostructure layers are optimized and the sensitivity (260°/RIU) and QF (48.14 RIU−1) of the proposed sensor with 48 nm Au, 6 nm ZnO, and a monolayer of BlueP-MoS2 (0.75 nm) are enhanced by 51.16% and 19.3% over the conventional SPR sensor. The rational design of the proposed SPR sensor delivering significantly large sensitivity is suited for experimental realization to deploy ZnO as an effective adhesive layer with the BlueP-MoS2 heterostructure for improved sensing performance.
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.
