Efficient light emission from inelastic tunneling junctions (Conference Presentation)
Author(s): Zhaowei Liu

Paper Abstract

Efficient light generation from inelastic electron tunneling (IET) using self-assembled edge-to-edge (EE) single-crystalline silver nanoparticles has been demonstrated with an efficiency up to ~2%. Various nanostructures including nanocube, nanobar, and square prism, have been explored, where the emission wavelengths covering from the visible to the near infrared. The excellent performance is attributed to the use of high-quality atomic level plasmonic cavities created within ultra-small gaps (~1.5 nm) as well as of optical nano-antenna formed by the EE nanoparticles. The realization of 2% efficiency based on IET brings on-chip ultrafast optical sources one step closer to reality.
