Surface plasmons excited via inelastic tunnelling have led to plasmon light sources with
small footprints and ultrafast response speeds, which are favored by integrated optical …

Light emission from ultracompact electrically driven optical antennas (EDOAs) has garnered
significant attention due to its terahertz modulation bandwidth. Typically, the EDOAs are …

Plasmonic nanogaps can support confined and enhanced electromagnetic fields. In this

Monolayer hexagonal boron nitride (h-BN) film generally has a weak interaction with
incident illumination because of its atomic thickness, which restricts its applications in …

In this article, we carry out an in-depth study of the scanning tunneling microscopy-induced
luminescence spectra (STML) of individual plasmonic nanoparticles measured in air. When …

Metal-insulator-metal tunnel junctions (MIM-TJs) can electrically excite surface plasmon
polaritons (SPPs) well below the diffraction limit. When inelastically tunneling electrons …
