Book excerpt: LES PROPRIETES DES COUCHES MINCES POLYCRISTALLINES DE SELENIUM HEXAGONAL PURES OU DOPEES PAR UN HALOGENE (IODE OU CHLORE) DEPOSEES PAR EVAPORATION THERMIQUE CLASSIQUE ONT ETE ETUDIEES EN FONCTION DE LA TEMPERATURE DU SUBSTRAT LORS DU DEPOT, DE LA NATURE DU SUBSTRAT ET DU DOPAGE DES COUCHES. LES EFFETS DES RECUITS SUR LES PROPRIETES STRUCTURALES ET OPTIQUES DE COUCHES MINCES DE SELENIUM PUR OU DOPE A L'IODE SONT ETUDIES PAR DIFFRACTION DE RAYONS X, MICROSCOPIE A BALAYAGE, SPECTROSCOPIE DE PHOTOELECTRONS (XPS), SPECTROSCOPIE RAMAN ET TRANSMISSION OPTIQUE. PARALLELEMENT L'EVOLUTION DE L'EPAISSEUR ET DU POIDS DES COUCHES EN FONCTION DE LA TEMPERATURE ET DE LA DUREE DU RECUIT EST CONTROLEE. DANS LE CAS DES COUCHES DOPEES A L'IODE, LES MODIFICATIONS DES PROPRIETES OPTIQUES SONT DUES A UNE COALESCENCE DES MICROCRISTALLITES, FACILITEE PAR LA SUBLIMATION DE L'IODE PRESENT DANS LES COUCHES. LA TEMPERATURE DE SEUIL NECESSAIRE POUR MODIFIER LA MORPHOLOGIE DES COUCHES DE SELENIUM, AVEC FORMATION DE TROUS, EST ABAISSEE PAR LA PRESENCE D'IODE DANS LES COUCHES. LA RESISTANCE ELECTRIQUE EST CONTROLEE PAR CONDUCTION PAR SAUTS AUX BASSES TEMPERATURES (80-190K) ET PAR DIFFUSION AU NIVEAU DES JOINTS DE GRAINS AUX TEMPERATURES SUPERIEURES. IL EST MONTRE QUE LE PHENOMENE DE SAUT, LE PLUS PROBABLE, EST CELUI CONTROLE PAR L'INTERACTION ELECTROSTATIQUE ENTRE LES ELECTRONS LOCALISES DANS LA BANDE INTERDITE. LES ANALYSES XPS EN FONCTION DU TEMPS DE DECAPAGE DES INTERFACES, COUCHE MINCE DE SELENIUM/COUCHE MINCE DE METAL (NICKEL, ALUMINIUM, TELLURE) ONT MONTRE QU'IL N'Y A AUCUNE FORMATION DE COMPOSES METAL-SELENIUM, LA SURFACE DU METAL ETANT PASSIVEE PAR LA FORMATION D'OXYDE. LES CARACTERISTIQUES I-V DE STRUCTURES NI/SE/CR ET BI/SE/CR PEUVENT ETRE BIEN DECRITES PAR LA THEORIE CLASSIQUE DE TRANSPORT DANS LES JONCTIONS SCHOTTKY: J EXP (QV/NKT) AVEC N=1,1 ET 1,5 RESPECTIVEMENT.

Book Synopsis The Physics of Selenium and Tellurium by : W. Charles Cooper
Download or read book The Physics of Selenium and Tellurium written by W. Charles Cooper and published by Elsevier. This book was released on 2013-09-11 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Physics of Selenium and Tellurium contains the proceedings of the International Symposium on the Physics of Selenium and Tellurium held in Montreal, Canada, on October 12-13, 1967 and sponsored by the Selenium-Tellurium Development Association, Inc. The papers explore the physics of selenium and tellurium, with emphasis on band structure, crystal growth and characterization, optical properties, and electrical properties. This book consists of 33 chapters and opens with a review of progress in the physics of selenium and tellurium, particularly with respect to the mechanical and thermal properties of trigonal selenium and tellurium and their lattice dynamics. The following chapters focus on calculations of the band structure of selenium and tellurium; magnetoabsorption in tellurium; trapping levels in hexagonal selenium; and coordination and thermal motion in crystalline selenium and tellurium. Infrared-active lattice vibrations in amorphous selenium and the contribution of lattice vibrations to the optical constants of tellurium are also discussed. This monograph will be a useful resource for physicists.

Available in PDF, EPUB and Kindle. Book excerpt: Our knowledge of the chemistry of selenium and tellurium has seen significant progress in the last few decades. This monograph comprises contributions from leading scientists on the latest research into the synthesis, structure and bonding of novel selenium and tellurium compounds. It provides insight into mechanistic studies of these compounds and describes coordination chemistry involving selenium and tellurium containing ligands. Contributions also describe the theoretical and spectroscopic studies of selenium and tellurium compounds. Additionally, this monograph outlines the applications of selenium and tellurium in biological systems, materials science and as reagents in organic synthesis and shows how these applications have been a fundamental driving force behind the research into the inorganic and organic chemistry these fascinating elements.

This book was released on 1996 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'APPLICATION DE COUCHES SUPERPOSEES SELENIUM AMORPHE (SE-A) / POLY(N-VINYLCARBAZOLE) (PVK) EST ENVISAGEABLE DANS LE DOMAINE DE LA XEROGRAPHIE. A CETTE FIN LES PROPRIETES DU PVK DOPE PAR UN HALOGENE ET LES CONTACTS METAL / SE-A ONT ETE ETUDIES. DANS UN PREMIER TEMPS LES PROPRIETES DU PVK EN POUDRE DOPE PAR UN HALOGENE (I, BR, CL) SONT ETUDIEES. IL EST MONTRE QUE SI UN SEL COMPLEXE A TRANSFERT DE CHARGE EST OBTENU DANS TOUS LES CAS, CELUI QUI EST OBTENU AVEC L'IODE EST LE PLUS INTERESSANT CAR IL NE DETRUIT PAS LE POLYMERE. IL PEUT ETRE STABILISE PAR TRAITEMENT THERMIQUE A 373 K. DES COUCHES MINCES DE PVK POST-DOPEES A L'IODE ONT ALORS ETE REALISEES. LEURS PROPRIETES SONT COMPAREES A CELLES DE COUCHES OBTENUES A PARTIR D'UNE POUDRE PREDOPEE. IL EST MONTRE QUE LA QUANTITE D'IODE PRESENT DANS LES COUCHES EST PLUS ELEVEE QUAND ELLES SONT POST-DOPEES. DE PLUS LEUR MORPHOLOGIE EST BEAUCOUP PLUS HOMOGENE ET REPRODUCTIBLE. SOUS CHAMP ELEVE LEUR CONDUCTIVITE EST DOMINEE PAR EFFET POOLE-FRENKEL. A LA TEMPERATURE AMBIANTE LEUR CONDUCTIVITE EST DE L'ORDRE DE 10#-#6 ( CM)#-#1 TANDIS QUE LE COMPLEXE I#- PVK#+ LES REND ABSORBANTES DANS LE VISIBLE CE QUI FAIT QU'ELLES SONT APPLICABLES A LA XEROGRAPHIE. PARALLELEMENT UNE ETUDE A ETE MENEE SUR LES CONTACTS M/SE-A (M=AL, AU, CR, SNO#2) ET M/PVK/SE-A. IL EST MONTRE QUE SEUL LE CONTACT AL/SE-A DONNE UN EFFET REDRESSEUR AVEC DES CARACTERISTIQUES REPRODUCTIBLES. CES CARACTERISTIQUES SONT OBTENUES APRES FORMATION ELECTRIQUE OU THERMIQUE QUI PERMET D'AMPLIFIER PUIS DE STABILISER L'EFFET REDRESSEUR. IL EST MONTRE PAR XPS QUE LE PROCESSUS DE FORMATION CORRESPOND A UNE INTERDIFFUSION AL/SE DANS LA ZONE OU L'ALUMINE EST PRESENT. PLUS PRECISEMENT L'XPS MONTRE QUE LA STRUCTURE DE L'OXYDE D'ALUMINIUM EST COMPLEXE. PROBABLEMENT CET OXYDE REAGIT AVEC LE SELENIUM AMORPHE POUR DONNER LE CONTACT REDRESSEUR EN NEUTRALISANT UN CERTAIN NOMBRE DE DEFAUTS PRESENTS DANS LA BANDE INTERDITE DU SELENIUM. LES CARACTERISTIQUES I-V DES STRUCTURES AL/SE-A NE SUIVENT PAS LES LOIS CLASSIQUES DES DIODES SCHOTTKY IL EST PROPOSE QUE LE PIEGEAGE DE PORTEURS MAJORITAIRES A L'INTERFACE AL/OXYDE, MODIFIE LA HAUTEUR DE BARRIERE LORS DE L'APPLICATION DE LA TENSION
