This book was released on 1998 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL CONCERNE UNE ETUDE FONDAMENTALE ET APPLIQUEE DES DEPOTS DE NICKEL CHIMIQUE AVEC INCORPORATION DE PARTICULES MINERALES, PLUS PARTICULIEREMENT LES PARTICULES DE SIC, DANS LE BUT D'OBTENIR DES INFORMATIONS SUR LEUR MECANISME D'INCLUSION DANS LES DEPOTS. BIEN QUE LA SURFACE DES POUDRES DE SIC SOIT FAIBLEMENT ET NEGATIVEMENT CHARGEE, LA PRESENCE DE NICKEL ADSORBES A ETE MIS EN EVIDENCE. CETTE ADSORPTION PEUT D'UNE PART FAVORISER LE DEPLACEMENT DES PARTICULES VERS LA SURFACE METALLIQUE PAR ATTRACTION ELECTROSTATIQUE. D'AUTRE PART, LES IONS NICKEL PEUVENT ETRE REDUITS EN NICKEL METALLIQUE, ET DE CE FAIT, PROMOUVOIR L'INCORPORATION DES PARTICULES DANS LA MATRICE. POUR OBTENIR UNE EPAISSEUR IMPORTANTE DES DEPOTS ET UN TAUX ELEVE DE PARTICULES DANS LA MATRICE, IL FAUT TRAVAILLER AVEC UN FAIBLE DEBIT DU BAIN. CECI EST A RELIER A UNE NOTION DE TEMPS DE CONTACT NECESSAIRE AUX PARTICULES AVEC LA SURFACE A RECOUVRIR POUR UNE BONNE INCLUSION PAR PIEGEAGE MECANIQUE DE LA MATRICE METALLIQUE EN CROISSANCE. L'INFLUENCE DE CERTAINS PARAMETRES SUR LE PROCESSUS DE LA FORMATION DU DEPOT TELS QUE LA TEMPERATURE DE MISE EN OEUVRE DES REVETEMENTS, LA CONCENTRATION EN PARTICULES DANS LE BAIN ET LA VITESSE DE DEPOT EST MONTREE. LES RESULTATS OBTENUS SONT CONFRONTES POUR FAIRE LE PARALLELE ENTRE CODEPOTS CHIMIQUES ET ELECTROLYTIQUES. POUR EXPLIQUER LE MODE D'INCORPORATION DES PARTICULES DE SIC DANS LE DEPOT DE NICKEL, UN MODELE MECANISTIQUE ELECTROLYTIQUE BASE SUR DEUX ETAPES D'ADSORPTION, EST ADAPTE A NOTRE CAS DE DEPOT CHIMIQUE. IL EST VALIDE EXPERIMENTALEMENT. QUELQUES CARACTERISTIQUES DE DURETE ET DE RESISTANCE A L'USURE PAR FROTTEMENT DES REVETEMENTS DE NICKEL-SIC SONT OBTENUES AVANT D'ETUDIER LEUR STRUCTURE. LA REPARTITION GRANULOMETRIQUE DES PARTICULES DANS LES DEPOTS EST COMPAREE A LA TAILLE DE LA POUDRE PRISE ISOLEMENT. IL APPARAIT QUE LES PARTICULES S'INCORPORENT SOUS FORME RELATIVEMENT BIEN ISOLEE ET DISPERSEE.

Book excerpt: Since the late 20th century, graphene-a one-atom-thick planar sheet of sp2-bonded carbon atoms densely packed in a honeycomb crystal lattice-has garnered appreciable attention as a potential next-generation electronic material due to its exceptional properties. These properties include high current density, ballistic transport, chemical inertness,

This book was released on 2014-01-10 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les nanotechnologies apportent un fort potentiel d’innovation et de rupture dans de nombreux domaines. Leurs applications pour l’énergie en est un champ important, car la synthèse et la structuration des nanomatériaux y ouvrent des voies de progrès notables. Si divers ouvrages décrivent les innovations promises par les nanotechnologies sur des thématiques scientifiques générales ou spécialisées, très peu abordent le chemin qui va des nouvelles propriétés aux applications pour l’énergie électrique et ses usages. Cet ouvrage présente, sur des bases scientifiques solides, les apports des nanotechnologies et plus particulièrement des nanomatériaux aux enjeux de la production d’électricité et de ses usages. Après un panorama des effets physiques qui peuvent être exploités à ces échelles pour améliorer les propriétés des matériaux ou leur fonctionnalité, leur application à la production d’électricité, à son stockage, à ses usages ainsi qu’au traitement de questions environnementales est abordée. Elle conduit à explorer les domaines de l’électrochimie, du photovoltaïque, de la thermoélectricité, des propriétés mécaniques et thermiques des matériaux ou encore des membranes et des surfaces ultrahydrophobes. Chaque chapitre constitue une monographie exhaustive enrichie d’une abondante iconographie et d’une bibliographie très complète. Les meilleurs experts de chaque domaine ont été réunis, faisant de cet ouvrage une référence incontournable. Au confluent de plusieurs disciplines et en prise directe sur un vaste champ d’applications, ce livre s’adresse à un large public : ingénieurs et chercheurs, étudiants des écoles d’ingénieurs ou des universités aux niveaux licence et master.

Available in PDF, EPUB and Kindle. Book excerpt: Silicon, as a single-crystal semiconductor, has sparked a revolution in the field of electronics and touched nearly every field of science and technology. Though available abundantly as silica and in various other forms in nature, silicon is difficult to separate from its chemical compounds because of its reactivity. As a solid, silicon is chemically inert and stable, but growing it as a single crystal creates many technological challenges. Crystal Growth and Evaluation of Silicon for VLSI and ULSI is one of the first books to cover the systematic growth of silicon single crystals and the complete evaluation of silicon, from sand to useful wafers for device fabrication. Written for engineers and researchers working in semiconductor fabrication industries, this practical text: Describes different techniques used to grow silicon single crystals Explains how grown single-crystal ingots become a complete silicon wafer for integrated-circuit fabrication Reviews different methods to evaluate silicon wafers to determine suitability for device applications Analyzes silicon wafers in terms of resistivity and impurity concentration mapping Examines the effect of intentional and unintentional impurities Explores the defects found in regular silicon-crystal lattice Discusses silicon wafer preparation for VLSI and ULSI processing Crystal Growth and Evaluation of Silicon for VLSI and ULSI is an essential reference for different approaches to the selection of the basic silicon-containing compound, separation of silicon as metallurgical-grade pure silicon, subsequent purification, single-crystal growth, and defects and evaluation of the deviations within the grown crystals.
