Silicon nanostructures, in the form of nanodots, nanowires and nanoslabs have attracted a
lot of interest in recent years. Quantum confinement effects play an important role with …

This report covers papers published in the period 2005–2007 on the application of
computational modelling to solids. The main areas of application chosen for review are …

We present a systematic study of the convergence with the supercell size of the defect
formation energy of a substitutional Al impurity in a Si nanowire within density-functional …

Nous avons effectué des calculs en théorie de la fonctionnelle de la densité et en théorie
des perturbations à plusieurs corps dans le but d'étudier les propriétés optiques de …

Within a first-principles framework we show the dependence of the optical properties of
silicon nanocrystallites embedded in a silica matrix on the crystalline vs. amorphous order of …

The study of semiconducting nanowires is one of the most rapidly growing research areas in
materials science and nanotechnology, not only from the point of view of the possible …

[eng] This Thesis has been focused on the fabrication and characterization of different
CMOS-compatible materials in order to determine both their electro-optical and resistive …
