This book was released on 1971 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using the van der Pauw method, Hall and resistivity measurements have been made on Zn- and Te-doped, epitaxially grown, single-crystal GaP. The measurements were made in the temperature range from 4 to 300K in the Zn-doped samples, and from 78 to 300K in the Te-doped samples. Room-temperature carrier concentrations ranged from 7 x 10 to the 15th power to 7 x 10 to the 18th power/cc in Zn-doped GaP and 4 x 10 to the 17th power to 2.7 x 10 to the 18th power/cc in Te-doped GaP. Variations of the ionization energies of Zn and Te with impurity concentration were determined from an analysis of the data. Room-temperature hole mobility in Zn-doped GaP varied from 60 to 100 sq cm/V-sec, and in Te-doped GaP from 11 to 91 sq cm/V-sec. The temperature dependence and magnitude of the mobility for both dopants are in good agreement with the calculated values of mobility due to scattering by acoustical and polar optical phonons at high temperatures. for by the mechanism of charged impurity scattering alone. The resistivity measurements of Zn-doped GaP below 78K show that GaP behaves as impure Ge does in the impurity-band conduction range. (Author).

Download or read book The Group 13 Metals Aluminium Gallium Indium and Thallium written by Simon Aldridge and published by John Wiley & Sons. This book was released on 2011-02-10 with total page 990 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last two decades have seen a renaissance in interest in the chemistry of the main group elements. In particular research on the metals of group 13 (aluminium, gallium, indium and thallium) has led to the synthesis and isolation of some very novel and unusual molecules, with implications for organometallic synthesis, new materials development, and with biological, medical and, environmental relevance. The Group 13 Metals Aluminium, Gallium, Indium and Thallium aims to cover new facts, developments and applications in the context of more general patterns of physical and chemical behaviour. Particular attention is paid to the main growth areas, including the chemistry of lower formal oxidation states, cluster chemistry, the investigation of solid oxides and hydroxides, advances in the formation of III-V and related compounds, the biological significance of Group 13 metal complexes, and the growing importance of the metals and their compounds in the mediation of organic reactions. Chapters cover: general features of the group 13 elements group 13 metals in the +3 oxidation state: simple inorganic compounds formal oxidation state +3: organometallic chemistry formal oxidation state +2: metal-metal bonded vs. mononuclear derivatives group 13 metals in the +1 oxidation state mixed or intermediate valence group 13 metal compounds aluminium and gallium clusters: metalloid clusters and their relation to the bulk phases, to naked clusters, and to nanoscaled materials simple and mixed metal oxides and hydroxides: solids with extended structures of different dimensionalities and porosities coordination and solution chemistry of the metals: biological, medical and, environmental relevance III-V and related semiconductor materials group 13 metal-mediated organic reactions The Group 13 Metals Aluminium, Gallium, Indium and Thallium provides a detailed, wide-ranging, and up-to-date review of the chemistry of this important group of metals. It will find a place on the bookshelves of practitioners, researchers and students working in inorganic, organometallic, and materials chemistry.

This book was released on 2013-11-11 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a joint effort of the Research Materials Information Center (RMIC) of the Solid State Division at Oak Ridge National Laboratory and the Libraries and Information Systems Center at Bell Telephone Laboratories (BTL) Murray Hill, N. J. The Research Materials Information Center has, since 1963, been answering inquiries on the avail ability, preparation, and properties of inorganic solid-state research materials. The preparation of bibliographies has been essential to this function, and the interest in ferroelectrics led to the compila tion of the journal and report literature on that subject. The 1962 book Ferroelectric Crystals, by Jona and Shirane, was taken as a cutoff point, and all papers through mid-1969 received by the Center have been included. The Libraries and Information Systems Center of BTL has, over a period of years, developed a proprie tary package of computer programs called BELDEX, which formats and generates indexes to biblio graphic material. This group therefore undertook to process RMIC's ferroelectric references by BELDEX so that both laboratories could have the benefit of an indexed basic bibliography in this important research area.
