研究方向

光在信息、化學、生命和材料等領域已經取得了巨大的套用。納米尺度的光場操控對於實現集成光傳輸、光學計算、生物樣品及材料的超靈敏感測以及太陽能電池的效率提升等具有重要的意義，然而納米尺度的光場具有極大的依賴表面等離激元效應。本課題組基於表面等離激元效應，開展以下幾個方面研究：
1. 研究基於電子顯微鏡的快電子與金屬納米結構作用過程，研究電子-光子相互作用及耦合機制。研究了利用快電子激發傳播表面等離激元 (Nano Lett. 9, 1176)、 在納米雙線中激發間隙表面等離激元(Phys. Rev. B 82, 125454) 、 在耦合納米粒子鏈中激發低損耗等離激元模式（Opt. Express 19, 18713）以及在耦合納米環中有效激發反對稱耦合表面等離激元 (Opt. Commun. 285, 4608)；在實驗利用陰極螢光光譜研究了金屬-介質-金屬結構中等離激元的色散（Phys. Rev. B 80, 033409）和等離激元準暗模的探測（Sci. Rep. 7, 1402)；理論預測了自由電子與等離激元之間角動量的高效轉移（Phys. Rev. B，In Press)。
2. 研究二維材料-石墨烯納微結構中的等離激元耦合以及相干效應。包括基本石墨烯納米結構（納米圓環、楔形波導和缺角圓盤）的等離激元回響 (Appl. Phys. Lett. 100, 153111, Opt. Express 21，32432, Opt. Commun. 355,10)、異質結構中石墨烯帶等離激元耦合效應 (Appl. Phys. Lett. 103, 041604, Opt. Express 22, 32450) 、等離激元與基底的耦合效應 (Opt. Lett. 37, 2730, Opt. Express 23, 29533) 、等離激元單向傳輸（Opt. Express 24, 19776，Opt. Express 25, 4680）、 石墨烯等離激元帶阻濾波器（Sci. Rep. 6, 26796）以及石墨烯光柵與石墨烯耦合的等離激元誘導透明效應（Opt. Express 24, 5875）等，同時在實驗上利用紅外波段的散射式近場顯微鏡研究了離子束誘導的缺陷對等離激元的反射的調控（Adv. Mater.29, 170,1083，2D Mater. 3, 045001, Nanotechnology DOI:10.1088/1361-6528/aad0b4）。
3. 提出基於金屬表面等離激元的場增強新機制和套用。包括利用表面等離激元Tamm態實現場增強（Sci. Rep. 6, 39152, JOSAB 31, 2796,JOSAB 35, 1368）和L-形等離激元腔（Opt. Express 24, 3849）等，同時實驗上提出了利用金屬納維結構的表面等離激元共振作為感測器的方案（Appl. Phys. Lett. 107, 091104, Appl. Phys. Lett. 108, 073106）。
