Electron Energy Loss Spectroscopy and Optical Properties of Plasmonic Nanostructure
… techniques have been applied to understand nanostructure’s plasmonic properties. Electron energy loss spectroscopy (EELS) is one of these tools, which is helpful for us to understand the interaction between fast moving electrons and nanomaterials. It could achieve very high spatial and …

On the nature of SERS from plasmonic nanostructures
… of surface-enhanced Raman scattering (SERS) on nanostructured surfaces is explored using both inorganic and organic-based systems and a variety of environmental perturbation mechanisms. Experimental optical characterisation systems are developed and existing systems extended to facilitate this …

OPTICAL PROPERTIES OF 2D TRANSITION METAL DICHALCOGENIDES ENHANCED BY PLASMONIC NANOSTRUCTURES
… and second harmonic generation (SHG) by gold plasmonic nanostructure with sub-20 nm-wide trenches. Additionally, we investigated the physics process of light-to-electron conversion in MoS2 on graphene by transient absorption spectroscopy. These interesting phenomena of PL, SHG and …

Time-domain Modeling of Light Matter Interactions in Active Plasmonic Metamaterials
… (FDTD)) of light matter interactions in active plasmonic metamaterials. In order to model the dispersion of plasmonic nanostructure in the time-domain, we introduce a generalized dispersive material model built on Padé approximants. The developed 3D FDTD solver is then applied to study several …

Surface plasmons for enhanced metal-semiconductor-metal photodetectors
… field enhancement. The emerging field of surface plasmonics has applied SPP coupling to a number of new and interesting applications, such as: Surface Enhanced Raman Spectroscopy (SERS), super lenses, nano-scale optical circuits, optical filters and SPP enhanced photodetectors. In the past decade, …

Studies on Optically Induced DC-Voltage in Thin Film Structures
… It works based on hot electron emission in plasmonic nanostructures. This photodetector, which is amenable to large-area fabrication, can be integrated with other nanophotonic and nanoplasmonic structures for operation at telecom wavelengths. I then show how an array of aligned plasmonic …
