Abstract

Metallic nanostructures can be designed to act not only as nanoscale optical antenna but also as much localized heat sources. Although both aspects are usually independently investigated, we conduct here a multiphysics approach to design multipurpose plasmonic nanogap antennas. On the one hand, by mean of a hydrothermal synthesis reaction, we make use of the localized heat production to control the growth of a ZnO layer at the surface of the targeted part of a gold nanoantenna. On the other hand, the fabricated hybrid plasmonic-photonic nanoantenna allows for large electric field enhancement inside ZnO-filled plasmonic nanogaps. Such nanodevice could find application as nanoscale light source.
