Abstract

Results are reported of an experimental study of the scattering and near-field interaction of a terahertz electromagnetic field with graphene ribbons near the metallic probe of an atomic-force microscope. It is shown that the near-field terahertz scattering in ribbons is enhanced in comparison with that in the case of an unstructured graphene. Resonance peaks at 0.2–1.6 THz appear in the spectra of terahertz radiation scattering on graphene ribbons in the presence of the probe, which is possibly due to the interaction of the radiation with plasmons in the ribbons.

石墨烯碳带中的太赫兹近场响应

摘要

据报道，实验研究了太赫兹电磁场与原子力显微镜金属探针附近的石墨烯带的散射和近场相互作用。结果表明，与非结构化石墨烯的情况相比，条带中的近场太赫兹散射得到增强。在存在探针的情况下，太赫兹辐射在石墨带上散射的太赫兹辐射光谱中出现了0.2–1.6 THz的共振峰，这可能是由于辐射与带中的等离子体激元的相互作用所致。
