摘要:

石墨烯是一种具有高迁移率和可调电导率的二维材料,特别适合于等离子体激元。体石墨烯中的等离子体激元的频率色散已经在理论和实验上进行了研究,而没有理论模型已经被报道,并针对石墨烯微结构中的受限等离子体激元模式的实验进行了测试。在本文中,我们提出了实验测量以及分析和计算模型,这样的限制模式。我们比较实验测量与理论的等离子体激元模式在相互作用的石墨烯条阵列,并表现出良好的协议。实验和理论结果之间的比较揭示了相邻石墨烯结构的等离子体激元模式之间的相互作用所发挥的重要作用。

英文摘要:

Graphene, a two-dimensional material with a high mobility and a tunable conductivity, is uniquely suited for plasmonics. The frequency dispersion of plasmons in bulk graphene has been studied both theoretically and experimentally, whereas no theoretical models have been reported and tested against experiments for confined plasmon modes in graphene microstructures. In this paper, we present experimental measurements as well as analytical and computational models for such confined modes. We compare experimental measurements with theory for plasmon modes in interacting arrays of graphene strips and demonstrate a good agreement. The comparison between experimental and theoretical results reveals the important role played by interaction among the plasmon modes of neighboring graphene structures.
