Quantum confinement effects in Pb Nanocrystals grown on InAs
Tianzhen Zhang, Sergio Vlaic, Stéphane Pons +9
In the recent work of Ref.\cite{Vlaic2017-bs}, it has been shown that Pb nanocrystals grown on the electron accumulation layer at the (110) surface of InAs are in the regime of Cou…
Dirac Cones, Topological Edge States, and Nontrivial Flat Bands in Two-Dimensional Semiconductors with a Honeycomb Nanogeometry
E. Kalesaki, C. Delerue, C. Morais Smith +3
We study theoretically two-dimensional single-crystalline sheets of semiconductors that form a honeycomb lattice with a period below 10 nm. These systems could combine the usual se…
Theoretical characterization of the electronic properties of extended thienylenevinylene oligomers
Christophe Krzeminski, Christophe Delerue, Guy Allan +5
We present semiempirical tight binding calculations on thienylenevinylene oligomers up to the hexadecamer stage (n=16) and ab initio calculations based on the local density approxi…
Theory of electrical rectification in a molecular monolayer
Christophe Krzeminski, Christophe Delerue, Guy Allan +2
The current-voltage characteristics in Langmuir-Blodgett monolayers of γ-hexadecylquinolinium tricyanoquinodimethanide (C16H33Q-3CNQ) sandwiched between Al or Au electrodes is calc…
Tight binding description of the electronic response of a molecular device to an applied voltage
Christophe Krzeminski, Christophe Delerue, Guy Allan
We analyze the effect of an external electric field on the electronic structure of molecules which have been recently studied as molecular wires or diodes. We use a self-consistent…
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…
