Momentum-resolved surface enhanced Raman scattering from a nanowire-nanoparticle junction cavity
Adarsh B. Vasista, Shailendra K. Chaubey, David J. Gosztola +3
Herein we report experimental evidence of directional SERS from molecules situated inside a single nanowire-nanoparticle junction cavity. The emission was confined to a narrow rang…
Plasmonic nanowire coupled to zero-dimensional nanostructures: A brief review
Sunny Tiwari, Chetna Taneja, G V Pavan Kumar
Metal nanowires and nanoparticles that facilitate surface plasmons are of contemporary interest in nanophotonics, thermoplasmonics and optoelectronics. They facilitate not only sub…
Broad Band Single Germanium Nanowire Photodetectors with Surface Oxide Controlled High Optical Gain
Shaili Sett, Ankita Ghatak, Deepak Sharma +2
We have investigated photoconductive properties of single Germanium Nanowires(NWs)of diameter less than 100 nm in the spectral range of 300 to 1100 nm showing ultra large peak Resp…
Wavevector analysis of plasmon-assisted distributed nonlinear photoluminescence along Au nanowire antennas
Deepak K. Sharma, Adrian Agreda, Julien Barthes +3
We report a quantitative analysis of the wavevector diagram emitted by nonlinear photoluminescence generated by a tightly focused pulsed laser beam and distributed along Au nanowir…
Dielectric microsphere coupled to a plasmonic nanowire: A self-assembled hybrid optical antenna
Sunny Tiwari, Chetna Taneja, Vandana Sharma +3
Hybrid mesoscale-structures that can combine dielectric optical resonances with plasmon-polaritons are of interest in chip-scale nano-optical communication and sensing. This experi…
Dielectric and Raman Spectroscopy in Hematite crystallites across the Morin Transition
Namrata Pattanayak, Jitender Kumar, Partha Pratim Patra +2
We report complex dielectric and Raman spectroscopy measurements in four samples of - FeO, consisting of crystallites which are either hexagonal shaped plates or cuboids…
