Size change effect on the optical behavior of ultra small metal particles
Mario Zapata-Herrera, Angela S. Camacho
In this paper we analyse the importance of a detailed description of the electronic transitions in ultra-small nanoparticles through the optical response to very small changes of s…

Near field enhancement due to the optical response of small nanoparticles
Mario Zapata-Herrera, Jefferson Flórez, Angela Camacho +1
In this work we study the strong confinement effects on the electromagnetic response of metallic nanoparticles. We calculate the field enhancement factor for nanospheres of various…

Electronic structure and band gap composition-dependence of the II-VI quaternary alloys
A. E. Garcia, A. Zepeda-Navratil, A. Camacho +2
Based on a successful description of II-VI ternary alloys, which introduces an empirical bowing parameter to the widely used virtual crystal approximation, we set up a tight-bindin…
