光在信息、化学、生命和材料等领域已经取得了巨大的应用。纳米尺度的光场操控对于实现集成光传输、光学计算、生物样品及材料的超灵敏传感以及太阳能电池的效率提升等具有重要的意义,然而纳米尺度的光场具有极大的依赖表面等离激元效应。本课题组基于表面等离激元效应,开展以下几个方面研究:

1. 研究基于电子显微镜的快电子与金属纳米结构作用过程,研究电子-光子相互作用及耦合机制。研究了利用快电子激发传播表面等离激元 (Nano Lett. 9, 1176)、 在纳米双线中激发间隙表面等离激元(Phys. Rev. B 82, 125454) 、 在耦合纳米粒子链中激发低损耗等离激元模式(Opt. Express 19, 18713)以及在耦合纳米环中有效激发反对称耦合表面等离激元 (Opt. Commun. 285, 4608);在实验利用阴极荧光光谱研究了金属-介质-金属结构中等离激元的色散(Phys. Rev. B 80, 033409)和等离激元准暗模的探测(Sci. Rep. 7, 1402);理论预测了自由电子与等离激元之间角动量的高效转移(Phys. Rev. B,In Press)。

2. 研究二维材料-石墨烯纳微结构中的等离激元耦合以及相干效应。包括基本石墨烯纳米结构(纳米圆环、楔形波导和缺角圆盘)的等离激元响应 (Appl. Phys. Lett. 100, 153111, Opt. Express 21,32432, Opt. Commun. 355,10)、异质结构中石墨烯带等离激元耦合效应 (Appl. Phys. Lett. 103, 041604, Opt. Express 22, 32450) 、等离激元与基底的耦合效应 (Opt. Lett. 37, 2730, Opt. Express 23, 29533) 、等离激元单向传输(Opt. Express 24, 19776,Opt. Express 25, 4680)、 石墨烯等离激元带阻滤波器(Sci. Rep. 6, 26796)以及石墨烯光栅与石墨烯耦合的等离激元诱导透明效应(Opt. Express 24, 5875)等,同时在实验上利用红外波段的散射式近场显微镜研究了离子束诱导的缺陷对等离激元的反射的调控(Adv. Mater.29, 170,1083,2D Mater. 3, 045001, Nanotechnology DOI:10.1088/1361-6528/aad0b4)。

3. 提出基于金属表面等离激元的场增强新机制和应用。包括利用表面等离激元Tamm态实现场增强(Sci. Rep. 6, 39152, JOSAB 31, 2796,JOSAB 35, 1368)和L-形等离激元腔(Opt. Express 24, 3849)等,同时实验上提出了利用金属纳维结构的表面等离激元共振作为传感器的方案(Appl. Phys. Lett. 107, 091104, Appl. Phys. Lett. 108, 073106)。
