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…
Large-scale optothermal assembly of colloids mediated by a gold microplate
Vandana Sharma, Diptabrata Paul, Shailendra K Chaubey +2
Light-activated colloidal assembly and swarming can act as model systems to explore non-equilibrium state of matter. In this context, creating new experimental platforms to facilit…
Directional out-coupling of light from a plasmonic nanowire-nanoparticle junction
Danveer Singh, Arindam Dasgupta, Aswathy V. G. +2
We experimentally show how a single Ag nanoparticle (NP) coupled to an Ag nanowire (NW) can convert propagating surface plasmon polaritons to directional photons. By employing dual…
