Available in PDF, EPUB and Kindle. Book excerpt: Ce travail s'inscrit dans le cadre général de l'exploration de nouvelles voies de synthèse originales de nanostructures de silicium ou de germanium. Ces méthodes d'oxydation mettent à profil les fortes propriétés réductrices des phases de Zintl, utilisées comme précurseurs. Aussi bien pour les nanomatériaux de silicium que de germanium, plusieurs voies de synthèse ont été mises au point et ensuite transposées à la synthèse de nanoparticules mixtes germanium/silicium. L'influence des paramètres réactionnels sur l'homogénéité, la forme et la cristallinité des nanostructures a été étudiée. Les matériaux ont été caractérisés par diffraction des Rayons X, diffraction électronique, microscopie électronique à transmission et spectroscopie Raman. L'application de ces nanostructures a été envisagée au sein de batteries à ions lithium, leur comportement électrochimique vis-à-vis du lithium s'est révélé très intéressant en dépit d'une importante capacité irréversible et d'une faible cyclabilité

Available in PDF, EPUB and Kindle. Book excerpt: Nanostructured silicon-germanium (SiGe) opens up the prospects of novel and enhanced electronic device performance, especially for semiconductor devices. Silicon-germanium (SiGe) nanostructures reviews the materials science of nanostructures and their properties and applications in different electronic devices. The introductory part one covers the structural properties of SiGe nanostructures, with a further chapter discussing electronic band structures of SiGe alloys. Part two concentrates on the formation of SiGe nanostructures, with chapters on different methods of crystal growth such as molecular beam epitaxy and chemical vapour deposition. This part also includes chapters covering strain engineering and modelling. Part three covers the material properties of SiGe nanostructures, including chapters on such topics as strain-induced defects, transport properties and microcavities and quantum cascade laser structures. In Part four, devices utilising SiGe alloys are discussed. Chapters cover ultra large scale integrated applications, MOSFETs and the use of SiGe in different types of transistors and optical devices. With its distinguished editors and team of international contributors, Silicon-germanium (SiGe) nanostructures is a standard reference for researchers focusing on semiconductor devices and materials in industry and academia, particularly those interested in nanostructures.
