摘要:
Collective oscillations of free electrons generate plasmons on the surface of a material. A whispering-gallery microcavity effectively confines the light field on its surface based on the total reflection from its internal wall. When these two kinds of electromagnetic waves meet each other, the stimulated emissions from an individual ZnO microrod were enhanced more than 50-fold and the threshold was reduced after the whispering-gallery microcavity was coated with a monolayer of graphene and Al nanoparticles. The improvement of the lasing performance was attributed to the synergistic energy coupling of the graphene/Al surface plasmons with ZnO excitons. The lasing characteristics and the coupling mechanism were investigated systematically.
摘要(中文):
免费电子的集体摆动在材料的表面上产生电浆子。耳语画廊 microcavity 有效地从它的内部墙基于全部的思考在它的表面上限制轻地。当这些二种电磁波遇见对方时,多于在耳语画廊 microcavity 与 graphene 和艾尔 nanoparticles 的单层是涂的以后, 50 褶层和阀值被减少,从单个 ZnO microrod 的刺激排出物被提高。放射激光的表演的改进被归因于与 ZnO 激子 graphene/Al 表面电浆子联合的 synergistic 精力。放射激光的特征和联合机制系统地被调查。
