Silicon nanowires coated with silver nanostructures as ultrasensitive interfaces for surface-enhanced Raman spectroscopy

E. Galopin, J. Barbillat, Yannick Coffinier, Sabine Szunerits, G. Patriarche, Rabah Boukherroub

Silver nanoparticles (Ag NPs) were chemically deposited on silicon nanowires (SiNWs), prepared using the vapor−liquid−solid (VLS) growth mechanism, using an in situ electroless metal deposition technique. The resulting SiNWs/Ag NPs composite interfaces showed large Raman scattering enhancement for…

Schottky barrier lowering with the formation of crystalline Er silicide on n-Si upon thermal annealing

N. Reckinger, X.H. Tang, V. Bayot, Dmitri Yarekha, S. Godey, Emmanuel Dubois, X. Wallart, G. Larrieu, A. Laszcz, J. Ratajczak, P.J. Jacques, J.P. Raskin

The evolution of the Schottky barrier height (SBH) of Er silicide contacts to n-Si is investigated as a function of the annealing temperature. The SBH is found to decrease substantially from 0.43 eV for as-deposited samples to reach its lowest value, 0.28 eV, at 450°C. By x-ray diffraction, high…

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…

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…
