Graphene-modulated surface plasmon resonance thermal absorption for high-precision refractive index sensing
This work presents the graphene-based surface plasmon resonance (SPR) thermal absorption for sensing, combining the SPR with a graphene-layered structure. Within a specific terahertz frequency range. Two thermal absorption peaks are formed by different resonance modes, and the corresponding electric field intensity distributions are analyzed to explain the observed phenomena. The sensor's performance for detecting analytes with varying refractive indices around it is investigated, demonstrating excellent sensing capabilities. The first resonance peak has a sensitivity (S) of 6 THz/RIU, a full-width at half maximum (FWHM) of 0.0146 THz, and a figure of merit (FOM) of 410.96 RIU−1. The second resonance peak exhibits a S of 6 THz/RIU, a FWHM of 0.0027 THz, and an FOM of 2222.22 RIU−1. The tuning of the sensor's peak position is achieved by adjusting the Fermi level of the graphene. To assess the performance deviations due to manufacturing errors, structural parameters of the sensor are also studied. This sensor demonstrates promising sensing performance and holds great potential for applications in sensing, environmental monitoring, and detection fields.
期刊介绍:
The International Journal of Thermal Sciences is a journal devoted to the publication of fundamental studies on the physics of transfer processes in general, with an emphasis on thermal aspects and also applied research on various processes, energy systems and the environment. Articles are published in English and French, and are subject to peer review.
The fundamental subjects considered within the scope of the journal are:
* Heat and relevant mass transfer at all scales (nano, micro and macro) and in all types of material (heterogeneous, composites, biological,...) and fluid flow
* Forced, natural or mixed convection in reactive or non-reactive media
* Single or multi–phase fluid flow with or without phase change
* Near–and far–field radiative heat transfer
* Combined modes of heat transfer in complex systems (for example, plasmas, biological, geological,...)
* Multiscale modelling
The applied research topics include:
* Heat exchangers, heat pipes, cooling processes
* Transport phenomena taking place in industrial processes (chemical, food and agricultural, metallurgical, space and aeronautical, automobile industries)
* Nano–and micro–technology for energy, space, biosystems and devices
* Heat transport analysis in advanced systems
* Impact of energy–related processes on environment, and emerging energy systems
The study of thermophysical properties of materials and fluids, thermal measurement techniques, inverse methods, and the developments of experimental methods are within the scope of the International Journal of Thermal Sciences which also covers the modelling, and numerical methods applied to thermal transfer.
