Borophene and Phase Change Material-based Integrated Multilayered High-Sensitive Refractive Index Sensor for Infrared Frequency Spectrum
This work presents the design and numerical simulation of a multilayered surface plasmon resonance (SPR) sensor incorporating borophene and germanium (Ge)-antimony (Sb) telluride (Te) (GST) as active plasmonic materials. The sensor design is modelled in two dimensions (2D) and exhibits a broad refractive index detection range, from 1 to 2.5 µm/RIU. The proposed design utilizes a top-analyte configuration, where the target analyte is placed directly on the sensor surface for interaction. Various metals like Ag (silver), Au (gold), Al (aluminium), and Cu (copper) are considered for investigation of the influence of the middle metal layer on the overall optical response. The GST layer is modelled as a two-state material, accounting for its amorphous (aGST) and crystalline (cGST) phases. It allows for exploring the sensor’s tunability based on the GST material’s phase state. Furthermore, comprehensive optimization and validation processes are conducted for various device parameters, including layer thicknesses, widths, and the type of metal employed. These optimizations aim to achieve optimal sensor performance regarding sensitivity and overall functionality. Notably, the simulations reveal distinct bandwidths and resonant regions for both aGST and cGST phases of the GST layer. In conclusion, this proposed sensor provides potential application in biomolecular and chemical testing due to its tunable characteristics and broad refractive index detection range.
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.
