Research problems linked to this topic
- Plasmonic waveguides is a hot topic in the field of photonic devices due to the ability to provide signal propagation in nanoscales beyond the diffraction limit.
- Plasmonic materials are intensively used to extend the photoactivity of large bandgap semiconductors into the visible light region.
- In order to reduce specific contact resistance at via/interconnect interface and to avoid device degradation with Cu diffusion into dielectrics, via cleaning technology is a critical issue for a scaled down Cu multilevel metallization.
- Modulating light via coherent charge oscillations in solids is the subject of intense research topics in opto-plasmonics.
- Inspection tools for nano-particle contamination on a planar substrate surface is a critical problem in micro-electronics.
- Fano resonance has been considered especially in nanostructures for energy enhancement and creating hot spots in nanoparticles based on plasmonic properties.
- Frequency selective surfaces (FSSs) are spatial filters widely employed in high-performance applications like hybrid radomes for radars and antennas.
- Reflection by wafer topography and underlying layers during optical lithography can cause unwanted overexposure in the resist.
- We have solved the problem in which a thin metal wafer (probe) with a nanohole interacts with the flat surface of a metastructured film consisting of metal nanoparticles in an external optical radiation field.
- The spectral shift between near- and far-field responses of the plasmonic nanoantennas has negative effects on the performance of surface-enhanced spectroscopy measurements.
- Raman scattering and surface-enhanced Raman scattering (SERS) have attracted the attention of researchers due to the great potential applications in various research fields, including biomolecular sensing, analytical chemistry, surface science and material science.
- Efficiently exciting surface plasmon polaritons (SPP) is highly desired in many photonic applications, but most approaches (such as prism and grating couplers) cannot control flexibly their SPP excitation directions.
- Metal nanocrystals with well-controlled shape and unique localized surface plasmon resonance (LSPR) properties have attracted tremendous attention in both fundamental studies and applications.
- The fabrication of complex, three-dimensional microscale shapes that can be replicated over large surfaces is an ongoing challenge, albeit one with a wide range of possible applications such as engineered surfaces with tuned wetting properties, scaffolds for cell studies, or surfaces with tailored optical properties.
- Although the surface Plasmon resonance (SPR) sensor is a mature technology, currently, the sample temperature needs to be carefully considered and controlled because SPR signals vary with temperature.
- As a remarkable class of plasmonic materials, two dimensional (2D) semiconductor compounds have attracted attention owing to their controlled manipulation of plasmon resonances in the visible light spectrum, which outperforms conventional noble metals.
