Integrated Surface-Enhanced Raman Spectroscopy Sensors for Process Monitoring

Zhang K., Zhang X., Rabin O., Zhang K., Zhang X., Briber R.M., von Bredow H., Metting C., Atanasoff G., University of Maryland, US

Optical metamaterials obtain their unique properties from the combination of nanoscale plasmonic components and dielectric components. Reproducible mass-production of metamaterials is challenging but desirable for applications such as surface-enhanced Raman scattering (SERS) for chemical sensing. [...]

Ion beam sputter deposition technique for direct growth of Ge quantum dots on a graphene/SiO2/Si substrate

Yang Y., Yunnan University, CN

The quantum dots (QDs)/graphene hybrid structure shows excellent photoresponse abilities in photodefectivity devices due to the unique QDs quantum confinement and the ultrahigh carrier mobility of graphene. Thus, this project invented the ion beam sputtering [...]

Theoretical Comparison of Optical and Photothermal Properties of Near-Infrared Plasmonic Nanoparticles

Liu K., Xue X., Furlani E.P., University at Buffalo, US

In this presentation, we use 3D computational models to compare the optical and photothermal behavior of plasmonic nanostructures that are commonly used for near-infrared (NIR) applications. These include SiO2@Au core-shell, Au nanocage and Au nanorod [...]

Self-Assembly and Optical Behavior of Magnetic-Plasmonic Nanostructures

Liu K., Xue X., Sukhotskiy V., Furlani E.P., University at Buffalo, US

We introduce a bottom-up method for the fabrication of nanostructured photonic media and demonstrate proof-of-principle using a multiphysics modeling approach. The method involves magnetic field-directed self-assembly of magnetic-plasmonic core-shell particles (e.g. Fe3O4@Au) into extended particle [...]

Indium Nitride Nanowire Growth by Chemical Vapor Deposition and Electrical Characterization

Teker K., Moussa O., Ali Y.A., Otto J., Istanbul Sehir University, TR

The III-nitrides have been intensely studied due to their wide range of applications from high efficiency solid-state lighting and photovoltaics to high-power and high temperature electronics. InN has received great attention due to its unique [...]

Highly luminescent Ca3Sc2Si3O12:Ce3+ silicate garnet nano- and microparticles with 50-70% photoluminescence quantum yields as efficient phosphor converters for white LEDs

Levchuk I., Schröppel F., Römling L., Osvet A., Khaidukov N., Zorenko Y., Van Deun R., Batentschuk M., Brabec C.J., University of Erlangen-Nuremberg, DE

Solid state lighting based upon a combination of violet/blue light emitting diodes (LEDs) and a phosphor converter created enormous commercial interest because of the potentially higher efficacies and long lifetimes of these light sources. Most [...]

Silk biocomposites as flexible and biodegradable electrochemical sensors

Pal R.K., Yadavalli V.K., Virginia Commonwealth University, US

The convergence of naturally derived and synthetic polymers provides exciting opportunities to develop physiologically compliant bioelectronics systems. The combination of silk proteins and poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) enables the formation of functional biocomposites with unique properties. [...]

Aerosol Jet Printed Functional Nanoinks with High Reliability and Reconfigurability

Lan X., Nguyen E., Malingowski A., Gambin V., Tice J., Northrop Grumman Aerospace Systems, US

Printed electronic components have long been desired in the aerospace industry to enable prototyping, design verification, and concept validation at a much more rapid pace than photolithography or manual wire bonding processes. For satellites that [...]
