A biomarker is a physiological observable marker that acts as a stand-in and, in the best-
case scenario, forecasts a clinically significant outcome. Diagnostic biomarkers are more …

Surface plasmon polaritons (SPPs) can achieve light transmission beyond the diffraction
limit due to their special dispersion relationship. As a novel two-dimensional material …

Collective oscillations of massless particles in two-dimensional (2D) Dirac materials offer an
innovative route toward implementing atomically thin devices based on low-energy …

Photodetectors based on two-dimensional (2D) materials such as monolayer MoS2 are
attractive because they can be directly integrated into the current metal-oxide semiconductor …

Single-layer graphene has many remarkable properties but does not lend itself as a material
for light-emitting devices as a result of its lack of a band gap. This limitation can be overcome …

Quantum tunneling-driven optical nanoantennas are key components for the development of
integrated plasmonic nanodevices. In this work, we use the tunneling junction between a …

Quantum tunneling, in which electrons can tunnel through a finite potential barrier while
simultaneously interacting with other matter excitation, is one of the most fascinating …

The understanding of and control over light emission from quantum tunneling has
challenged researchers for more than four decades due to the intricate interplay of electrical …

In recent years, tunnel junctions have reemerged as promising candidates for the
transduction of electrical to optical signals at the nanoscale. The process of interest is known …

At the interfaces of metal and dielectric materials, strong light–matter interactions excite
surface plasmons; this allows electromagnetic field confinement and enhancement on the …
