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.…

Excitonic and quasiparticle gaps in Si nanocrystals

Christophe Delerue, Michel Lannoo, Guy Allan

We present calculations of the one- and two-particle excitations in silicon nanocrystals. The one-particle properties are handled in the GW approximation, and the excitonic gap is obtained from the Bethe-Salpeter equation. We develop a tight binding version of these methods to treat clusters up to…
