研究目的
Investigating the tunable plasmonic properties of graphene ribbon for hypersensitive nanosensing in the infrared region.
研究成果
The study demonstrates that graphene ribbon metamaterials can achieve high sensitivity in plasmonic sensing, with single layer asymmetrical structures showing superior performance. This paves the way for tunable graphene-based devices in infrared sensing applications.
研究不足
The study is limited to numerical simulations using the FDTD method, and practical implementation may face challenges in fabricating the precise graphene structures and achieving the desired chemical potential variations.
1：Experimental Design and Method Selection:
The study employs the three-dimensional finite-difference time-domain (FDTD) method to investigate plasmonic sensing based on symmetrical and asymmetrical graphene metamaterials.
2：Sample Selection and Data Sources:
The unit cell structure is composed of two parallel graphene ribbons and strips, with variations in chemical potential and structure symmetry.
3：List of Experimental Equipment and Materials:
Graphene ribbons, glass substrate, and AlO23 strips are used.
4：Experimental Procedures and Operational Workflow:
Simulations are conducted with varying chemical potentials and refractive indices to observe transmission resonance dip shifts.
5：Data Analysis Methods:
The sensitivity of the proposed metamaterial is calculated based on the shift in transmission resonance dips.
