This book was released on 2013 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail de thèse a pour but la mise au point et l’optimisation d’un nouveau procédé de dépôt de couches minces d’oxyde de zinc pour des applications photovoltaïques. Le principe de ce procédé, nommé « Spray Plasma », consiste à injecter un aérosol de microgouttelettes d’une solution aqueuse de nitrate ou chlorure de zinc dans un réacteur plasma basse pression. Sous l’effet de l’évaporation rapide et la réactivité du plasma d’argon/oxygène, le précurseur de zinc est transformé en couches minces d’oxyde sur la surface du substrat à température contrôlée. La transformation chimique fait intervenir des radicaux d’oxygène, de OH, des électrons, et des espèces excitées d’argon ou d’oxygène. La caractérisation expérimentale de la décharge par spectroscopie d’émission et par sonde de Langmuir nous a permis de déterminer les paramètres plasma tels que la température électronique (2-4 eV), la température du gaz (400 K), la densité des ions ainsi que l’évolution des espèces réactives du plasma. Parallèlement, ont été développés un modèle hydrodynamique pour calculer l’évolution de la taille et de la température des gouttelettes dans le réacteur d’une part, et un modèle cinétique en volume pour calculer l’évolution des paramètres du plasma d’autre part. La caractérisation des films par différentes techniques (DRX et MEB) nous a montré l’obtention de films nanostructurés avec des vitesses de dépôt de l’ordre de 90 nm/min. Le contrôle des paramètres de dépôt tels que la température du substrat, la concentration en précurseur et la fraction d’oxygène, permet de contrôler l’orientation cristalline, l’épaisseur, la rugosité et la taille des grains des films. Nous avons étudié le rôle de chaque paramètre sur la croissance des films et leurs propriétés structurales, optiques et électriques et corrélé ces résultats avec les caractéristiques du plasma.

Book Synopsis Materials Syntheses by : Ulrich Schubert
Download or read book Materials Syntheses written by Ulrich Schubert and published by Springer Science & Business Media. This book was released on 2008-11-23 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Materials syntheses are more complex than syntheses of inorganic or organic compounds. Materials synthesis protocols often suffer from unclarities, irreproducibility, lack in detail and lack in standards. The need to change this situation is the main motivation for this book. It collects a number of detailed protocols, ranging from organic polymers to carbonaceous and ceramic materials, from gels to porous and layered materials and from powders and nanoparticles to films.
Book Synopsis Physical Properties of Amorphous Materials by : David Adler

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.
