Mendes, MJ, A. Luque, I. Tobias, and A. Marti. "{Plasmonic light enhancement in the near-field of metallic nanospheroids for application in intermediate band solar cells}." Applied Physics Letters. 95 (2009): 71105. Abstract

In order to enhance infrared light absorption in sub-bandgap transitions in an intermediate band solar cell, the scattered near-field potential from uncoated and coated metallic nanoparticles with a spheroidal shape is calculated with the electrostatic model. The absorption enhancement produced at the surface plasmon frequency of the nanoparticles can be of several orders of magnitude in some cases.

Luque, A., A. Marti, MJ Mendes, and I. Tobias. "{Light absorption in the near field around surface plasmon polaritons}." Journal of Applied Physics. 104 (2008): 8. Abstract

A semiclassical method is developed to calculate the energy absorption of an electronic system located in the near field of a metal nanoparticle sustaining surface plasmons. The results are found to be similar to those of photon absorption from ordinary transversal radiation. However, they are affected by a geometrical factor that can increase the absorption by several orders of magnitude. As example, we investigate ellipsoidal-shaped metal nanoparticles which, under favorable conditions, may provide near field aborption enhancements almost as large as 10(4), and in many cases above 10.
