Abstract

We show that scanning electron microscopy imaging can indicate hot-electron formation in aluminum plasmonic nanostructures composed of five triangular cavities. A very strong secondary electron emission was observed, up to 150 nm from the plasmonic structure. The secondary electron emission depends on the acceleration voltage, the distance between the plasmonic cavities, the metal type, and the roughness of the surface. Furthermore, the formation of hot electrons was used to increase the efficiency of an optoelectronic device.
