Resonance Light Scattering in Dye-Aggregates Forming in Dewetting Droplets

Gian-Luca Bona, Roland Hany, Jakob Heier, Raffaele Mezzenga

Small organic semiconducting molecules assembling into supramolecular J- and H- aggregates have attracted much attention due to outstanding optoelectronic properties. However, their easy and reproducible fabrication is not yet sufficiently developed for in ...

Definition of the radiation fields for the JET gamma-ray spectrometer diagnostics

Patrick Blanchard

The JET gamma-ray diagnostics system provides information on the behaviour of fast particles within the tokamak plasma. Information on the spatial distribution of the interacting fast particles is obtained from the gamma-ray cameras, while energy distribut ...

Vertical "III-V" V-Shaped Nanomembranes Epitaxially Grown on a Patterned Si[001] Substrate and Their Enhanced Light Scattering

Anna Fontcuberta i Morral, Martin Heiss, Eleonora Russo, Sonia Conesa Boj, Anna Dalmau Mallorquí, Ludovit Pavel Zweifel

We report on a new form of III-IV compound semiconductor nanostructures growing epitaxially as vertical V-shaped nanomembranes on Si(001) and study their light-scattering properties. Precise position control of the InAs nanostructures in regular arrays is ...

Integrated computational approaches for spectroscopic studies of molecular systems in the gas phase and in solution: pyrimidine as a test case

Fabio Trani

An integrated computational approach built on quantum mechanical (QM) methods, purposely tailored inter-and intra-molecular force fields and continuum solvent models combined with time-independent and timedependent schemes to account for nuclear motion eff ...

Photocurrent spectroscopy of site-controlled pyramidal quantum dots

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Pascal Gallo, Jérôme Faist, Arun Mohan

Intraband photocurrent spectroscopy of site-controlled pyramidal quantum dots by inserting them into the intrinsic region of n-i-n like quantum dot infrared photodetector structure is reported. The photovoltaic response is observed in the mid-infrared regi ...

Variable delay using stationary and localized Brillouin dynamic gratings

Luc Thévenaz, Nikolay Primerov

Reflections from movable, dynamic acoustic gratings in polarization maintaining (PM) fibers are employed in the long variable delay of periodic, isolated pulses. The gratings are introduced by stimulated Brillouin scattering (SBS) interaction between two c ...

Structural slow light can enhance Beer-Lambert absorption

Luc Thévenaz, Sang Hoon Chin, Isabelle Dicaire

We experimentally demonstrate that structural slow light can enhance Beer-Lambert absorption. A 4-fold reduction of the group velocity induced by mere cavity effects has caused an increase of molecular absorption by 130%. ...
