纳米粒子间范德华力的等离子体性质
Plasmonic nature of van der Waals forces between nanoparticles
摘要:
我们提出了一种新的方法来计算纳米粒子之间的范德华力的范德华能量可以减少到纳米粒子中的基本表面等离子体激元振荡的能量。应用一般理论描述了两个金属纳米颗粒之间以及纳米颗粒与理想导电平面之间的相互作用。我们的研究结果可用于实验证明等离子体分子的存在,并制定新的控制机制,相互之间或表面上的纳米粒子的粘附。
英文摘要:
We propose a new approach to calculate van der Waals forces between nanoparticles where the van der Waals energy can be reduced to the energy of elementary surface plasmon oscillations in nanoparticles. The general theory is applied to describe the interaction between 2 metallic nanoparticles and between a nanoparticle and a perfectly conducting plane. Our results could be used to prove experimentally the existence of plasmonic molecules and to elaborate new control mechanisms for the adherence of nanoparticles between each other or onto surfaces.
