金属纳米粒子的光电发射

Photoemission from metal nanoparticles

Igor E. Protsenko, Alexander V. Uskov

摘要:

考虑到局域等离子体激元共振(LPR)的激发以及金属-环境界面处电磁场(EMF)和传导电子质量的变化,讨论并推广了A.Brodsky和Yu.Gurevitch的方法用于金属纳米颗粒的光电发射。新的结果是由于纳米颗粒表面附近电动势强度的增加以及上述表面现象,光电发射电流分别比连续金属膜的情况增加了几倍。研究结果可应用于开发新的光电探测器,光能转换器(太阳能电池)和更多的研究从金属纳米粒子的光电发射。

英文摘要:

A.Brodsky and Yu.Gurevitch approach is discussed and generalized for photoemission from metal nano-particles taking into account the excitation of localized plasmon resonance (LPR) and changes of electromagnetic field (EMF) and conduction electron mass in the metal - environment interface. New result is the increase of photo-emission current several time respectively to the case of continues metal film due to increase of intensity of EMF near the surface of nanoparticles and also due to surface phenomena mentioned above. Results can be applied for development new photodetectors, photo energy converters (solar cells) and for more studies of photoemission from metal nanoparticles.
