研究目的
Investigating the application of tunable plasmon resonance in graphene for designing multi-purpose beam-forming metasurfaces and dynamic label-free detection of trace gas at terahertz and mid-infrared frequencies.
研究成果
Graphene plasmonics offers a versatile platform for tunable beam-forming metasurfaces and sensitive gas detection. The ability to dynamically tune plasmon resonance without altering geometric features opens new avenues for all-purpose beam forming and label-free gas sensing applications.
研究不足
The applicability of graphene plasmon-based SEIRA spectroscopy to the gas phase is less effective due to weaker dielectric response of gases. The study focuses on mid-infrared and terahertz frequencies, which may limit its application in other spectral regions.
