论文摘要
我们研究了一层被铜氧化物Cu $ _2 $ o包围的铜层中表面等离子体（SPP）的传播。结果表明，Cu $ _2 $ O中特别强大的激子对等离子体的传播产生相当大的影响，为等离子体exciton和等离子体播种机相互作用提供了许多机会。可以证明，通过使用足够薄的金属层，可以激发所谓的远距离等离子体（LRSPPS），与通常的等离激元金属（如银）相比，可以克服固有的Cu固有高欧姆损失。分析结果通过数值计算证实。
We investigate the propagation of surface plasmons (SPPs) in a thin layer of copper surrounded by copper oxide Cu$_2$O. It is shown that particularly strong excitons in Cu$_2$O can have considerable impact on plasmon propagation, providing many opportunities for plasmon-exciton and plasmon-plasmon interactions. It is demonstrated that by the use of sufficiently thin metal layer, one can excite the so-called long range plasmons (LRSPPs) which can overcome the inherently high ohmic losses of Cu as compared to usual plasmonic metals such as silver. Analytical results are confirmed by numerical calculations.
