    01.08.09 — Architecture, Civil and Environmental Engineering | ENAC The FP6 project TOCSIN, directed by the Economics and Environmental Management Laboratory (REME), evaluated climate change mitigation options in China and India. In particular, it investigated the strategic dimensions of cooperation in research, development and tech transfer, and the challenge of creating incentives to encourage developing countries to participate in post-2012 greenhouse gas emissions reductions.

    14.07.09 — Nanophotonics and Metrology We present a systematic numerical investigation of conical metal tips which are commonly used in tip-enhanced Raman spectroscopy (TERS). Different from previous studies, we focus on how the tip length and the illumination condition influence the local field enhancement at the tip apex, and provide a useful reference for real experiments. In particular, we show that the type of illumination has a dramatic influence on the field enhancement: a localized illumination spot—as used in experiments—producing a very different response than a plane wave illumination—as usually used in previous models. Also, the effect of the different geometrical parameters, such as the sharpness of the tip apex and the cone angle, provides guidance to optimize the tip design. Finally, we investigate the influence of the substrate and compare numerical data with results deduced from a simplified model, finding good agreement. This brings new insights into the enhancement mechanism of TERS. Read the whole article

    02.07.09 — Nanophotonics and Metrology Mode-selective surface-enhanced Raman spectroscopy (SERS) is demonstrated using plasmonic dipole antennas fabricated with electron beam lithography. An 10× change of the relative enhancement between two different Raman modes is observed when the resonance frequency of the plasmonic antennas is tuned over the Raman modes by varying the geometrical parameters of the antennas, i.e., changing their lengths or narrowing their feeding gaps. The comparison between the Rayleigh scattering spectra and the SERS spectra from the same individual plasmonic dipole antennas indicates that this mode-selective SERS phenomenon is a pure electromagnetic effect, providing a quantitative verification of the electromagnetic mechanism of SERS on a single nanoantenna level.
