报告摘要:
Plasmonicsdealswith the phenomena of collective vibration of electrons in the interfacebetween metallic and dielectric media. With the advanced nanofabricationtechniques, a broad variety of nanostructures can be designed and fabricatedfor plasmonic investigations at nanoscale. In thispresentation, we will demonstrateour latest results of the design ofnew plasmonic nanostructures andthecharacterization ofsurfaceplasmon nanostructures with 2D materials by usingScanningNear-field Optical Microscopy (SNOM),whichis one of the uniquecharacterization tools for nano-optical detection,and other techniques,and discuss some fundamentalproperties for both localized surface plasmons and surface plasmon polaritonsarise a new insight and understanding for the electro-optical devices, such asactive plasmonic modulator and plasmonic detectors for energy harvesting.
