摘要:

等离子体波在各种金属量子纳米结构中的传播因其在技术上的应用而受到关注。金属纳米结构在量子尺寸范围内的量子等离激元性质一直难以用合适的模型来描述。在这里,非局域量子等离子体激元研究在最重要的金属铜,金,银。利用一种新的非局域量子介电常数模型研究了这些金属的色散特性和高光子能区纵向量子等离子体激元的传播。研究了这些金属中纵向量子等离子体激元的近零特性,得到了它们的光谱和阻尼率。量子等离子体的波函数的经典和量子极限。结果表明,银是最适合的量子金属结构的发展,下一代的量子光学和传感技术,由于低的本征损耗。

英文摘要:

The propagation of plasmonic waves in various metallic quantum nanostructures have considered attention for their applications in technology. The quantum plasmonic properties of metallic nanostructures in the quantum size regime have been difficult to describe by an appropriate model. Here the nonlocal quantum plasmons are investigated in the most important metals of copper, gold, and silver. Dispersion properties of these metals and propagation of longitudinal quantum plasmons in the high photon energy regime are studied by a new model of nonlocal quantum dielectric permittivity. The epsilon near zero properties are investigated and the spectrum and the damping rate of the longitudinal quantum plasmons are obtained in these metals. The quantum plasmon s wave function is shown for both classical and quantum limits. It is shown that silver is the most appropriate for quantum metallic structures in the development of next generation of quantum optical and sensing technologies, due to low intrinsic loss.
