A 3D Plasmonic Antenna-Reactor for Nanoscale Thermal Hotspots and Gradients

Plasmonic nanoantennas focus gentle beneath the diffraction restrict, creating sturdy subject enhancements, usually inside a nanoscale junction. Inserting a nanostructure throughout the junction can tremendously improve the nanostructure’s innate optical absorption, leading to intense photothermal heating that would in the end compromise each the nanostructure and the nanoantenna. Right here, we exhibit a three-dimensional “antenna-reactor” … Read more
