Oscillatory Size-Dependence of the Surface Plasmon Linewidth in Metallic Nanoparticles
, 2002 We study the linewidth of the surface plasmon resonance in the optical absorption spectrum of metallic nanoparticles, when the decay into electron-hole pairs is the dominant channel. Within a semiclassical approach, we find that the electron-hole density-

Impact of strain on the excitonic linewidth in transition metal dichalcogenides [PDF]
2D Materials, 2018 Monolayer transition metal dichalcogenides (TMDs) are known to be highly sensitive to externally applied tensile or compressive strain. In particular, strain can be exploited as a tool to control the optical response of TMDs.
