Near Kohn anomalies in the phonon dispersion relations of lead chalcogenides

Ondrej Kilian, Guy Allan, Ludger Wirtz

We present ab-initio phonon dispersion relations for the three lead chalcogenides PbS, PbSe, and PbTe. The acoustic branches are in very good agreement with inelastic neutron-scattering data and calculations of the specific heat give good agreement with experimental data. The pronounced minimum of...

Recent ROB developments on wide bandgap based UV sensors

B. Giordanengo, A. Ben Moussa, Jean-François Hochedez, A. Soltani, P. de Moor, K. Minoglou, P. Malinowski, J.Y. Duboz, Y.M. Chong, Y.S. Zou, W.J. Zhang, S.T. Lee, R. Dahal, J. Li, J.Y. Lin, H.X. Jiang

The next ESA spatial mission planned to study the Sun, Solar Orbiter (SO), necessitates very innovative EUV detectors. The commonly used silicon detectors suffer important limitations mainly in terms of UV robustness and dark current level. An alternative comes from diamond or III-nitride materials...

From rejection to transmission for a stack of arrayed split ring resonators

Jorge Carbonell, Eric Lheurette, Charles Croënne, Vicente Boria, Didier Lippens

We report on free space transmission experiments carried out on stacked split ring resonator (SRRs) arrays operating at microwaves. We start from the case of a single frequency selective surface which exhibits a rejection at the SRR resonance frequency. By stacking several SRR arrays in the...

Electron-phonon coupling and intervalley splitting determine the linewidth of single-electron transport through PbSe nanocrystals

Karin Overgaag, Daniel Vanmaekelbergh, Peter Liljeroth, Gauthier Mahieu, B. Grandidier, Christophe Delerue, Guy Allan

The linewidth of the resonances in the single-electron tunneling spectra has been investigated for PbSe semiconductor nanocrystals (NCs) with scanning tunneling spectroscopy at low temperature. The linewidth of the resonances corresponding to tunneling through the first conduction and valence...
