Plasmonic Hot Hole Generation by Interband Transition in Gold-Polyaniline

Studies on hot carrier science and technology associated with various types of nanostructures are dominating today's nanotechnology research. Here we report a novel synthesis of polyaniline-gold (PAni-Au) nanocomposite thin films with gold nanostructures (AuNs) of desired shape and size uniformly incorporated in the polymer matrix. According to shape as well as size variation of AuNs, two tunab...

Surface-Plasmon-Enhanced Third-Order Harmonic Generation of Organic Materials

We design and fabricate metallic photonic crystals that are integrated with highly-efficient third-order nonlinear polymers. Compared with nanoparticle-doped composite materials, metallic photonic crystals are favorable due to the presence of Bragg-grating-modulated surface plasmon polaritons (SPPs) with strong light localization in large spatial volumes to uniformly enhance the harmonic signal...

Interband contribution to transition radiation from metals

2014 Emission spectra from aluminium and copper targets excited by fast electrons have been measured. The ratio of these two measurements can be directly compared with theoretical transition radiation calculations. A well pronounced shoulder is observed at 2.1 eV giving the first experimental evidence of interband contribution to transition radiation. J. Physique LETTRES 43 (1982) L-733 L-737 C...

Symmetry-selective third-harmonic generation from plasmonic metacrystals.

Nonlinear processes are often governed by selection rules imposed by the symmetries of the molecular configurations. The most well-known examples include the role of centrosymmetry breaking for the generation of even harmonics, and the selection rule related to the rotational symmetry in harmonic generation for fundamental beams with circular polarizations. While the role of centrosymmetry brea...

Enhanced second-harmonic generation from individual metallic nanoapertures.

We demonstrate the ability of single-subwavelength-size nanoapertures fabricated in a gold metal thin film to enhance second-harmonic generation (SHG) as compared to a bare metal film. Nonlinear microscopy imaging with polarization resolution is used to quantify the SHG enhancement in circular and triangular nanoaperture shapes. The dependence of the measured SHG enhancement on circular apertur...
