Theoretical Analysis of Metallic-Nanodimer Thermoplasmonics for Phototactic Nanoswimmers

Autor: Raúl A. Bustos-Marún, Nicolás Passarelli, Andrés I. Bertoni

Publikováno v: ACS Applied Nano Materials. 3:1821-1829

We assess the potentiality of several geometries of metallic nanodimers (one of the simplest thermoplasmonic systems) as candidates for active particles (nanoswimmers) propelled and controlled by light (phototaxis). The studied nanodimers are formed

Theoretical Study of a Cylindrical Graphene-based Localized Surface Plasmon Spaser

Autor: Leila Prelat, Ricardo A. Depine, Nicolás Passarelli, Mauro Cuevas, Raúl A. Bustos Marún

Publikováno v: Frontiers in Optics / Laser Science.

We consider a dielectric active wire coated with a graphene monolayer. Using rigorous electromagnetic methods, we present theoretical results which illustrate the non-radiative transfer between the active medium and the graphene localized surface pla

The decomposition of gold hydroxide to give metallic gold is known to take place around 300 °C in dry environments. However, little information about the gold hydroxide stability in wet environments has been recorded. Here, we present experimental e

Spaser and Optical Amplification Conditions in Gold-Coated Active Nanoparticles

Autor: Eduardo A. Coronado, Nicolás Passarelli, Raúl A. Bustos-Marún

Publikováno v: The Journal of Physical Chemistry C. 120:24941-24949

Due to their many potential applications, there is an increasing interest in studying hybrid systems composed of optically active media and plasmonic metamaterials. In this work we focus on a particular system which consists of an optically active si
