This book was released on 1990 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: LE BUT DE CE MEMOIRE EST D'ETUDIER LES PHENOMENES DE TRANSITION CRISTAL-AMORPHE INDUITS PAR IMPLANTATION D'IONS LEGERS DANS LE SILICIUM. DANS UNE PREMIERE PARTIE, NOUS NOUS INTERESSONS AUX PERTES D'ENERGIE SUBIES PAR LA PARTICULE INCIDENTE (INTERACTIONS ION-MATIERE) AINSI QU'AUX MECANISMES QUI PEUVENT CONDUIRE A LA TRANSITION CRISTAL-AMORPHE. LES MODELES PERMETTANT DE DECRIRE QUANTITATIVEMENT LA FORMATION ET L'EXTENSION DE COUCHES AMORPHES SONT AUSSI PASSES EN REVUE. DANS LA PARTIE EXPERIMENTALE, NOUS AVONS MIS EN EVIDENCE L'APPORT DE LA MICROSCOPIE ELECTRONIQUE EN TRANSMISSION A LA CARACTERISATION DE L'AMORPHISATION DU SI PAR IMPLANTATION D'IONS PHOSPHORE, AZOTE ET HELIUM DANS DES CONDITIONS EXPERIMENTALES DIVERSES (ENERGIE ET FLUX DU FAISCEAU D'IONS ET TEMPERATURE DU SUBSTRAT). L'UTILISATION DU MODELE DE LA DENSITE D'ENERGIE CRITIQUE NOUS A PERMIS DE CALCULER L'ETAT D'ENDOMMAGEMENT DU SUBSTRAT ET DE DETERMINER L'ENERGIE DE DOMMAGE CRITIQUE NECESSAIRE A LA FORMATION DE LA PHASE AMORPHE. NOUS AVONS MIS EN EVIDENCE QUE L'ENERGIE DE DOMMAGE EST UNE CARACTERISTIQUE DU SUBSTRAT A BASSE TEMPERATURE (

HECQUET and published by . This book was released on 1989 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: CE MEMOIRE CONCERNE L'ETUDE DE L'EMISSION ELECTRONIQUE SECONDAIRE (INCLUANT L'EMISSION AUGER) OBSERVEE LORS DE L'IRRADIATION DE CIBLES DE SI(111) PAR DES IONS DE GAZ RARES DE MOYENNE ENERGIE (5-80 KEV). SUR LE PLAN EXPERIMENTAL, L'EXPLOITATION DES DISTRIBUTIONS D'ENERGIE DES ELECTRONS SECONDAIRES CONDUIT A L'OBTENTION DES COEFFICIENTS D'EMISSION ELECTRONIQUE (NOMBRE D'ELECTRONS PAR ION INCIDENT) ET DES VALEURS ABSOLUES DES RENDEMENTS AUGER. LA VARIATION DE CES GRANDEURS EN FONCTION DE LA TEMPERATURE DE LA CIBLE PERMET DE DETERMINER LES TEMPERATURES DE TRANSITION DE PHASE CRISTAL-AMORPHE SOUS IRRADIATION. L'INFLUENCE DE L'ENERGIE, DE LA NATURE ET DE L'ANGLE D'INCIDENCE DU FAISCEAU SONT ETUDIEES. UN MODELE DE SIMULATION NUMERIQUE DE L'EMISSION AUGER A ETE ELABORE. IL EST BASE SUR LE DEVELOPPEMENT DES CASCADES DE COLLISIONS ATOMIQUES DANS LES SOLIDES (CODE MARLOWE). LA 1ERE PARTIE DE CE TRAVAIL FAIT LE POINR SUR LES CONNAISSANCES THEORIQUES ACTUELLES CONCERNANT L'INTERACTION D'IONS LOURDS ENERGETIQUES AVEC LA MATIERE CONDENSEE. L'ACCENT EST MIS PARTICULIEREMENT SUR LES PROBLEMES D'AMORPHISATION DE CIBLES SEMICONDUCTRICES. L'ENSEMBLE EXPERIMENTAL, DECRIT DANS LA 2EME PARTIE, SE COMPOSE D'UN ACCELERATEUR DE PARTICULES ET D'UNE ENCEINTE DE MESURE A ULTRAVIDE. UN SYSTEME D'ANALYSE A POTENTIEL RETARDATEUR AVEC DERIVATION ELECTRONIQUE ET DETECTION SYNCHRONE DONNE LA DISTRIBUTION D'ENERGIE DES ELECTRONS SECONDAIRES EMIS AVEC UNE ENERGIE COMPRISE ENTRE 0 ET QUELQUES CENTAINES EV. DANS UNE DERNIERE PARTIE, LES RESULTATS EXPERIMENTAUX SONT PRESENTES ET DISCUTES EN COMPARAISON AVEC LES DONNEES DU MODELE DE SIMULATION NUMERIQUE

Book excerpt: DANS CE TRAVAIL, NOUS NOUS SOMMES INTERESSES AUX MECANISMES DE RESTRUCTURATION DE COUCHES DE SILICIUM FORTEMENT ENDOMMAGEES PAR L'IMPLANTATION A L'ARSENIC. LES ECHANTILLONS CARACTERISES ONT ETE ELABORES A PARTIR D'UN SUBSTRAT DE SILICIUM 100 DE TYPE P BOMBARDE, A LA TEMPERATURE AMBIANTE, AVEC UN FAISCEAU D'IONS D'ARSENIC ACCELERE A 200 KEV. EN FAISANT VARIER LA DOSE D'IMPLANTATION, NOUS AVONS PU METTRE EN EVIDENCE, A L'AIDE DE LA MICROSCOPIE ELECTRONIQUE, LA TRANSITION CRISTAL-AMORPHE LORSQUE LA DOSE D'IMPLANTATION EST SUPERIEURE A LA DOSE CRITIQUE D'AMORPHISATION. LA COMBINAISON DE PLUSIEURS METHODES DE CARACTERISATION ELECTRIQUES ET PHYSIQUES NOUS A PERMIS D'ETUDIER L'EFFET DU RECUIT THERMIQUE POST-IMPLANTATION SUR LES PROPRIETES ELECTRIQUES ET STRUCTURALES DE CE MATERIAU. LA CORRELATION DES RESULTATS ISSUS DE CES DIFFERENTES METHODES A RENDU POSSIBLE LA MISE EN EVIDENCE D'UN PHENOMENE D'ACTIVATION ELECTRIQUE DES IMPURETES APRES RECUIT A BASSE TEMPERATURE INTERVENANT INDEPENDAMMENT DE LA RECRISTALLISATION DE LA COUCHE AMORPHE. L'ANALYSE DETAILLEE DE CE PHENOMENE A DEMONTRE QU'IL SE PRODUIT PAR UN PROCESSUS DE RELAXATION LOCALE CARACTERISEE PAR UNE FAIBLE ENERGIE D'ACTIVATION. L'ETUDE DE L'EFFET DU RECUIT THERMIQUE SUR LES PROPRIETES STRUCTURALES DES COUCHES DE SILICIUM DESORDONNE A PERMIS DE CONCLURE QUE LA MIGRATION DES DEFAUTS PONCTUELS ET DE LEURS COMPLEXES EST A L'ORIGINE DE LA RELAXATION LOCALE

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.

Book excerpt: "The Ladybird is a long tale or novella by D. H. Lawrence. It was first drafted in 1915 as a short story entitled The Thimble. Lawrence rewrote and extended it under a new title in December 1921 and sent the final version to his English agent on 9 January 1922. It was collected with two other tales, The Captain's Doll and The Fox, and the three novellas were then published in London by Martin Secker in March 1923 under the title The Ladybird and in New York by Thomas Seltzer as The Captain's Doll in April 1923."
