PDAF Pixel With Plasmonic Nanostructures

IEEE Sensors Journal
The sub micrometer pixel pitch of CMOS image sensors improves the resolution and functionality of image sensors. To achieve the high optical performance of sensors, optical characteristics, such as sensitivity and crosstalk, should be satisfied. However,

Shell‐Isolated Plasmonic Nanostructures for Biosensing, Catalysis, and Advanced Nanoelectronics

Advanced Functional Materials, 2020
Shell‐isolated nanostructures, consisting of an inert shell and a plasmonic core, have recently been intensively explored for biosensing, catalysis, and nanoelectronics applications owing to their functional shells and unique plasmonic properties.

Shelled Plasmonic Nanostructures

2019 XXIVth International Seminar/Workshop on Direct and Inverse Problems of Electromagnetic and Acoustic Wave Theory (DIPED), 2019
Plasmonic structures attract much interest because they present exotic properties in areas that are much smaller than a wavelength. They are attractive for different applications such as sensors, single molecule detection, near- field microscopy, enhanced Raman spectroscopy, etc.

Plasmonic holographic nanostructures

Optical Memory and Neural Networks, 2009
Surface plasmon resonance (SPR) in planar nanostructures is considered. SPR-based methods of measuring optical characteristics and thicknesses of nanolayers are given. Use of diffraction and holographic gratings comprised of small sub-gratings displaced perpendicular to the grooves is considered to achieve the fine structure of plasmonic resonance and ...

Tunable plasmonic nanostructures

2008 IEEE/LEOS International Conference on Optical MEMs and Nanophotonics, 2008
We discuss different composite plasmonic nanostructures, which optical properties can be tuned by displacing some of their parts at the nanoscale. The actuation of these structures with MEMs will define new optical functionalities.

Design and Performance Perspectives on Fiber Optic Sensors With Plasmonic Nanostructures and Gratings: A Review

IEEE Sensors Journal, 2019
This paper presents a sharp review of the current state-of-the-art related to the fiber optic sensors with (i) gratings (namely, fiber Bragg gratings, i.e., FBG and long period fiber gratings, i.e., LPG) and (ii) plasmonic nanostructures (metallic/non ...

Building plasmonic nanostructures with DNA

Nature Nanotechnology, 2011
Plasmonic structures can be constructed from precise numbers of well-defined metal nanoparticles that are held together with molecular linkers, templates or spacers. Such structures could be used to concentrate, guide and switch light on the nanoscale in sensors and various other devices.

Block-Copolymer-Based Plasmonic Nanostructures

ACS Nano, 2009
We report on the fabrication and optical characterization of dense and ordered arrays of metal nanoparticles. The metal arrays are produced by reducing metal salts in block copolymer (BCP) templates made by solvent annealing of poly(styrene-b-4-vinylpyridine) (PS-b-P4VP) or poly(styrene-b-ethylene oxide) (PS-b-PEO) diblock copolymer thin films in mixed

Nanorice:  A Hybrid Plasmonic Nanostructure

Nano Letters, 2006
We have designed and fabricated a new hybrid nanoparticle that combines the intense local fields of nanorods with the highly tunable plasmon resonances of nanoshells. This dielectric core-metallic shell prolate spheroid nanoparticle bears a remarkable resemblance to a grain of rice, inspiring the name "nanorice".

Gold-silver nanostructures: Plasmon-plasmon interaction

Vacuum, 2017
Abstract Gold and silver coupled nanostructure system presents immense possibilities for understanding plasmon-plasmon interaction in colloidal suspension. The origin of surface plasmon resonance (SPR) in noble metal nanostructures and the dependence of SPR on various factors have been widely investigated and the interactions of plasmons have also ...
