Paper Abstract

Electroluminescence based on inelastic tunnelling has been investigated for many years in scanning tunnelling microscopy (STM) and plasmonic antenna platforms. Here, we report an electrically excited nanosource with a bowtieshaped tunnel junction that has achieved an output power. The tunnel junction in our experiments is formed via an electromigration (EM) process. The benefits of our new structural design include higher tunnel currents, ultra-strong electrical field enhancement and a higher Purcell factor. By varying the geometric parameters of the plasmonic antenna, the energies of these LSP modes can be tuned for different confinement lengths.
