方柱形原子团簇中的纵向等离激元和横向等离激元
Longitudinal Plasmon and Transverse Plasmon in Square Cylinder
摘要: 基于自由电子气体模型和无规相近似下的线性响应理论，我们研究了方柱形原子团簇中的等离激元。结果发现，横向等离激元随柱长的增加而发生蓝移，而纵向等离激元随柱长的增加而发生红移。
Abstract: Based on the linear response theory in the random-phase approximation and the free-electron gas model, we study the plasmon excitations in square cylinder. Results show: when the length of square cylinder is increased, the frequency of longitudinal plasmon displays redshift, but the frequency of transverse plasmon shows blue shift.
