Quantum confinement in germanium nanocrystals

Yann-Michel Niquet, Guy Allan, Christophe Delerue, Michel Lannoo

The electronic structure of Ge nanocrystals is studied using a sp3 tight binding description. Analytical laws for the confinement energies, valid over the whole range of sizes, are derived. We validate our results with ab initio calculations in the local density approximation for smaller clusters.…

Nature of impurity states in doped amorphous silicon

Guy Allan, Christophe Delerue, Michel Lannoo

We calculate the electronic structure of doped amorphous silicon in a tight-binding framework. Substitutional impurities are randomly introduced at fourfold-coordinated sites of a previously published model of a-Si:H. Our most important result is that single impurities have much larger binding…

An ultra high switching frequency step-down DC-DC converter based on gallium arsenide devices

Mamadou Gaye, Sami Ajram, Paul Maynadier, Georges Salmer

A 50MHz to 100MHz dc-dc power converter using Gallium Arsenide power switches is studied. GaAs Schottky rectifiers with high breakdown voltage and very small Ron x Con switching quality factor have been fabricated. A 10V to 5V (or 8V) prototype with an output power of 2.6Watts and a power…
