Energy transfer between semiconductor nanocrystals : validity of Förster's theory

Guy Allan, Christophe Delerue

We theoretically study the energy transfer between semiconductor nanocrystals and we calculate the rate of this process in the case of direct-gap (InAs) and indirect-gap (Si) semiconductors. The calculations are based on the tight-binding method that enables us to determine the transfer rate,…

Ionization energy of donor and acceptor impurities in semiconductor nanowires: importance of dielectric confinement

Mamadou Diarra, Yann-Michel Niquet, Christophe Delerue, Guy Allan

Calculations of the electronic states of donor and acceptor impurities in nanowires show that the ionization energy of the impurities is strongly enhanced with respect to the bulk, above all when the wires are embedded in a material with a low dielectric constant. In free-standing nanowires with…

Imaging electron wave functions inside open quantum rings

F. Martins, B. Hackens, Marco G. Pala, Thierry Ouisse, Hermann Sellier, X. Wallart, S. Bollaert, A. Cappy, Joël Chevrier, V. Bayot, Serge Huant

Combining Scanning Gate Microscopy (SGM) experiments and simulations, we demonstrate low temperature imaging of electron probability density $|\Psi|^{2}(x,y)$ in embedded mesoscopic quantum rings (QRs). The tip-induced conductance modulations share the same temperature dependence as the Aharonov-…

1/f(gamma) tunnel current noise through Si-bound alkyl monolayers

N. Clement, S. Pleutin, O. Seitz, S. Lenfant, D. Vuillaume

We report low frequency tunnel current noise characteristics of an organic monolayer tunnel junction. The measured devices, n Si/alkyl chain (C18H37)/Al junctions, exhibit a clear 1/ f γ power spectrum noise with 1< γ <1.2. We observe a slight biasdependent background of the normalized…

Micrometric Ripples in a Capillary Tube, the Effect of Microgravity

Alain Merlen, Farzam Zoueshtiagh, Peter J. Thomas, V. Thomy

The oscillatory motion of a fluid carrying micron-sized particles inside a capillary tube is investigated experimentally in standard gravity condition. It is found that initially uniformly distributed particles can segregate and accumulate to form regularly spaced micron-sized particle clusters.…
