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-scatt…
Frequency-dependent spontaneous emission rate from CdSe and CdTe nanocrystals: influence of dark states
A. F. van Driel, G. Allan, C. Delerue +3
We studied the rate of spontaneous emission from colloidal CdSe and CdTe nanocrystals at room temperature. The decay rate, obtained from luminescence decay curves, increases with t…
Molecular rectifying diodes from self-assembly on silicon
Stephane Lenfant, Christophe Krzeminski, Christophe Delerue +2
We demonstrate a molecular rectifying junction made from a sequential self-assembly on silicon. The device structure consists of only one conjugated (p) group and an alkyl spacer c…
