The Role of Electron Transfer in the Nonlinear Response of Ge2Sb2Te5-Mediated Plasmonic Dimers
Here, we study the possibility of exquisitely selective harmonic generation based on the concept of charge transfer Vanadyl plasmons (CTPs) in bridged nanoparticle assemblies.By choosing plasmonic dimer nanoantenna, as a fundamental member of the nanocluster family, and bridging the capacitive gap space between the proximal nanoparticles with an op
