A Phonon Scattering Bottleneck for Carrier Cooling in Lead Chalcogenide Nanocrystals

Pieter Geiregat, Christophe Delerue, Yolanda Justo, Michiel Aerts, Frank Spoor, Dries van Thourhout, Laurens Siebbeles, Guy Allan, Arjan J Houtepen, Zeger Hens

The cooling dynamics of hot charge carriers in colloidal lead chalcogenide nanocrystals is studied by hyperspectral transient absorption spectroscopy. We demonstrate a transient accumulation of charge carriers at a high energy critical point in the Brillouin zone. Using a theoretical study of the…

High density terahertz frequency comb produced by coherent synchrotron radiation

S Tammaro, Olivier Pirali, P Roy, Jean-Francois Lampin, Guillaume Ducournau, Arnaud Cuisset, Francis Hindle, Gaël Mouret

Frequency combs have enabled significant progress in frequency metrology and high-resolution spectroscopy extending the achievable resolution while increasing the signal-to-noise ratio. In its coherent mode, synchrotron radiation is accepted to provide an intense terahertz continuum covering a wide…

Experimental analysis of Zigbee RF signal performance for railway application: Study on a laboratory reduced scale train

Sara Iben Jellal, O. Cohin, S. Baranowski, Ulrich Biaou, Michael Bocquet, Atika Rivenq

Due to its cost and power performance, Zigbee is widely used and can be applied to railway systems. This paper deals with the performance of a Zigbee (IEEE.802.15.4) RF signal, according to several criteria; this analysis is based on an experimental approach and specially on power measurements in…
