Book Synopsis Utilisation des plasmas micro-ondes RCE pour préparer des films minces de nitrure de silicium by : Mickael Lapeyrade
Download or read book Utilisation des plasmas micro-ondes RCE pour préparer des films minces de nitrure de silicium written by Mickael Lapeyrade and published by . This book was released on 1999 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette étude démontre la possibilité de déposer, à basse température (200-300°C) et avec une puissance micro-onde limitée (220 W), des films de nitrure de silicium de qualité électronique (résistivité de 1015 Q.cm) avec des propriétés physico-chimiques proches du nitrure de silicium stœchiométrique élaboré à haute température, et qui soit compatible avec une technologie de passivation de matériaux III-V. Des mesures par sonde de Langmuir ont permis de caractériser le plasma d'azote dans les conditions expérimentales utilisées. Une étude approfondie des propriétés électriques, structurales et physico-chimiques des films montre que les propriétés des films sont très dépendantes des paramètres de la source RCE et de la nature du substrat initial. Un procédé de passivation a été défini. Les traitements de surface combinent désoxydation chimique en voie humide et nitruration en voie sèche. Le dépôt de nitrure de silicium peut être réalisé depuis la température ambiante jusqu'à 300°C. Une étude des propriétés physico-chimiques et électriques des interfaces Si3N4/AlInAs et Si3N4/GaInAs a été réalisée. La préparation de surfaces idéales à partir de surfaces "technologiquement contaminées" et d'interfaces Si3N4/AlInAs et Si3N4/GaInAs de qualité à partir de surfaces vierges ou de surfaces technologiques, est délicate à optimiser, notamment en raison de la présence d'arsenic élémentaire, source d'états d'interfaces. Ce procédé de passivation a été appliqué avec succès sur des transistors HEMT et des photodiodes de la filière InGaAlAs/InP. Il est actuellement utilisé de façon courante au laboratoire pour passiver les composants optoélectroniques de type photodiodes.
Book Synopsis Ceramic Materials by : Philippe Boch
Download or read book Ceramic Materials written by Philippe Boch and published by John Wiley & Sons. This book was released on 2010-01-05 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is primarily an introduction to the vast family of ceramic materials. The first part is devoted to the basics of ceramics and processes: raw materials, powders synthesis, shaping and sintering. It discusses traditional ceramics as well as “technical” ceramics – both oxide and non-oxide – which have multiple developments. The second part focuses on properties and applications, and discusses both structural and functional ceramics, including bioceramics. The fields of abrasion, cutting and tribology illustrate the importance of mechanical properties. It also deals with the questions/answers of a ceramicist regarding electronuclear technology. As chemistry is an essential discipline for ceramicists, the book shows, in particular, what soft chemistry can contribute as a result of sol-gel methods.

This book was released on 2013-06-29 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Institute for Amorphous Studies was founded in 1982 as the international center for the investigation of amorphous mate rials. It has since played an important role in promoting the und er standing of disordered matter in general. An Institute lecture series on "Fundamentals of Amorphous Materials and Devices" was held during 1982-83 with distinguished speakers from universities and industry. These events were free and open to the public ,and were attended by many representatives of the scientific community. The lectures themselves were highly successful inasmuch as they provided not only formal instruction but also an opportunity for vigorous and stimulating debate. That last element could not be captured within the pages of a book I but the lectures concentrated on the latest advances in the field I which is why their essential contents are he re reproduced in collective form. Together they constitute an interdisciplinary status report of the field. The speakers brought many different viewpoints and a variety of back ground experiences io bear on the problems involved I but though language and conventions vary I the essential unity of the concerns is very clear I as indeed are the ultimate benefits of the many-sided approach.

Book Synopsis Cambridge Yearbook of European Legal Studies, Vol 13, 2010-2011 by : Catherine Barnard
Download or read book Cambridge Yearbook of European Legal Studies, Vol 13, 2010-2011 written by Catherine Barnard and published by Bloomsbury Publishing. This book was released on 2011-12-15 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambridge Yearbook of European Legal Studies provides a forum for the scrutiny of significant issues in EU Law, the law of the European Convention on Human Rights, and Comparative Law with a 'European' dimension, and particularly those issues which have come to the fore during the year preceding publication. The contributions appearing in the collection are commissioned by the Centre for European Legal Studies (CELS) Cambridge, a research centre in the Law Faculty of the University of Cambridge specialising in European legal issues. The papers presented are at the cutting edge of the fields which they address, and reflect the views of recognised experts drawn from the University world, legal practice, and the institutions of both the EU and its Member States. Inclusion of the comparative dimension brings a fresh perspective to the study of European law, and highlights the effects of globalisation of the law more generally, and the resulting cross fertilisation of norms and ideas that has occurred among previously sovereign and separate legal orders. The Cambridge Yearbook of European Legal Studies is an invaluable resource for those wishing to keep pace with legal developments in the fast moving world of European integration.
