In this paper, the scattering of a plane monochromatic electromagnetic wave from a nanowire with circular cross-section in the transverse electric (TE) mode is simulated using the well-known Stratton-Chu surface integral equations. For an ordinary dielectric nanowire the refraction phenomenon is nicely simulated. In the case of a plasmonic nanowire no sign of surface plasmon excitation and prop...

Solar steam generation has been achieved by surface plasmon heating with metallic nanoshells or nanoparticles, which have inherently narrow absorption bandwidth. For efficient light-to-heat conversion from a wider solar spectrum, we employ adiabatic plasmonic nanofocusing to attain both polarization-independent ultrabroadband light absorption and high plasmon dissipation loss. Here we demonstra...

Two- and four-probe electrical measurements on individual conjugated polymer nanowires with different diameters ranging from 20 to 190 nm have been performed to study their conductivity and nanocontact resistance. The two-probe results reveal that all the measured polymer nanowires with different diameters are semiconducting. However, the four-probe results show that the measured polymer nanowi...

A metallic nanowire with quantized conductance was fabricated by electrochemically etching a narrow portion of a metallic wire supported on a solid substrate down to the atomic scale. The width of the nanowire was controlled flexibly by etching atoms away or depositing atoms back onto the wire with the electrochemical potential. Using a feedback loop this method can, at will, fabricate a single...

Motivated by recent experiments that report the almost-generic large-conductance peaks without very extensive fine-tuning, we propose an alternative mechanism through direct theoretical simulations can explain large zero-bias conductance being generated on-demand in nontopological regime Majorana nanowires satisfying following three sufficient conditions: (i) strong potential disorder bulk of n...

Recently, topological insulators (Bi2Se3, Bi2Te3 and Sb2Te3) have attracted much attention because of their bulk band gap (0.3 eV) and spin-polarized surface states with conductive massless Dirac Fermions [1]. Interestingly, Bi2Se3 has rhombohedral crystal structure which consists of Se or Bi lattices in stacked manner with the sequence of Se-Bi-Se-Bi-Se. This forms a sheet-like structure in wh...

Abstract We report on the experimental observation of mirror-enhanced directional surface-enhanced Raman scattering (SERS) from a self-assembled monolayer molecules coupled to nanowire-nanoparticle (NW-NP) junction mirror in remote excitation configuration. Placing NW-NP metallic generates multiple gap plasmon modes that have unique momentum space-scattering signatures. perform Fourier plane im...
