This book was released on 2012-12-06 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The science of semiconducting materials is still very young. Less than twenty years ago, the school of A. F. loffe demonstrated that the properties of semiconductors are governed primarily by their chemical nature and can be predicted on this basis. These ideas are still be ing developed and used to establish a new materials science: the chemistry of semiconductors. The solution of problems in the chemistry of semiconductors should make it possible to find new applications for solids. We are already witnessing the process in which the practical importance of such new materials as diamond-like AlIIB V compounds is accelerating the de velopment of the chemistry and phYSics of semiconductors and some allied sciences. Diamond-like semiconductors are promising materials for modern electronics. They be long to an extensive class of valence compounds which seem to be an inexhaustible source of new semiconducting materials. Among these new, particularly promising materials, are ternary diamond-like semicon ductors, which are the subject of the present monograph. The appearance of this book, which is the first on this subject not only in the Soviet Union but also outside it, is the proof of the im portance attached to promising semiconductors in the USSR. The authors describe the methods for the preparation of compounds and the growth of single crystals. They analyze in detail the phYSicochemical and phYSical properties of ternary compounds and the relationships between these properties, and consider the possible applica tions of these substances and suggest further investigations.

Download or read book Ternary Alloys Based on II VI Semiconductor Compounds written by Vasyl Tomashyk and published by CRC Press. This book was released on 2013-07-29 with total page 563 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doped by isovalent or heterovalent foreign impurities (F), II–VI semiconductor compounds enable control of optical and electronic properties, making them ideal in detectors, solar cells, and other precise device applications. For the reproducible manufacturing of the doped materials with predicted and desired properties, manufacturing technologists need knowledge of appropriate ternary system phase diagrams. A guide for technologists and researchers at industrial and national laboratories, Ternary Alloys Based on II-VI Semiconductor Compounds collects all available data on ternary II–VI–F semiconductor materials. It presents ternary phase diagrams for the systems and includes data about phase equilibriums on the cross sections. The book is also suitable for phase diagram researchers, inorganic chemists, and solid state physicists as well as students in materials science, engineering, physical chemistry, and physics. The authors classify all materials according to the periodic groups of their constituent atoms (i.e., possible combinations of Zn, Cd, and Hg with chalcogens S, Se, and Te) and additional components in the order of their group number. Each ternary system database description contains the diagram type, possible phase transformation and physical–chemical interaction of the components, equilibrium investigation methods, thermodynamic characteristics, and the sample preparation method. In some cases, the book illustrates the solid and liquid-phase equilibriums with vapor because of their importance to crystal growth using the vapor–liquid–solid technique. It also presents data on the homogeneity range as well as baric and temperature dependences of solubility impurities in the semiconductor lattice and the liquid phase.

Download or read book Biohydrometallurgy of Chalcopyrite written by Hongbo Zhao and published by Elsevier. This book was released on 2021-07-29 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioleaching of chalcopyrite is always a challenge and research hotspot. The low copper extraction and dissolution kinetics restricted the industrial application of chalcopyrite bioleaching. To solve this problem, the dissolution process and passivation mechanism of chalcopyrite in bioleaching should be first studied, then the rate-limiting steps should be analysed explicitly, and finally the intensifying method can be put forward. Many scholars have made efforts to investigate the dissolution mechanism of chalcopyrite in bioleaching. However, there is no congruence of opinion as yet. Biohydrometallurgy of Chalcopyrite summarizes and discusses the reported research findings. In addition, this book publishes the related results found by the authors’ research. Then, the dissolution mechanism of chalcopyrite in bioleaching is interpreted. Finally, the process intensification techniques of chalcopyrite bioleaching are provided and discussed. Hence, this book provides useful reference and guidance in both laboratory research and industrial production. Interprets the dissolution mechanism of chalcopyrite in bioleaching Provides feasible technologies for intensifying chalcopyrite bioleaching Overviews the current situations of chalcopyrite bioleaching Helps the readers to deeply understand the bioleaching mechanisms of chalcopyrite Provides topics for future research and potential industrial applications
Download or read book Optical Properties of the Chalcopyrite Semiconductors CuInSe2 CuInS2 and CuGaSe2 written by Franziska Luckert and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: CuInSe2, CuInS2 and CuGaSe2 are I-III-VI2 compound semiconductors with a chalcopyrite structure. These ternary compounds exhibit favourable properties, such as direct band gaps and high absorption coefficients, for application as absorber layers in thin-film solar cells. Recently Cu(In,Ga)Se2 based photovoltaic devices have demonstrated conversion efficiencies of 20.3 % which is the highest amongst polycrystalline thin-film solar cell technologies. This thesis describes a study of excitonic recombination processes in high quality CuInSe2, CuInS2 and CuGaSe2 single crystals using photoluminescence (PL) spectroscopy as a function of excitation power, temperature and applied magnetic field. Excitation power dependent measurements confirm the identification of the free excitons in the PL spectra of the three chalcopyrite semiconductor compounds. Additional sharp lines in the PL spectra appear to be due to the radiative recombination of excitons bound to shallow hydrogenic defects. PL lines due to excitons bound to more complex defects with a low concentration of defects are also found in CuInSe2 and CuInS2. Analysis of the temperature dependent PL spectra lead to activation energies of the free and bound excitons in CuInSe2, CuInS2 and CuGaSe2. In addition, phonon energies have been obtained from the temperature dependence of the free exciton spectral positions and of the full width at half maximum. PL spectra measured in applied magnetic fields allow estimation of the diamagnetic shift rates for CuInSe2, CuInS2 and CuGaSe2. A first-order perturbation model leads to values for the excitonic reduced masses and the effective hole masses can be estimated. For CuInSe2 a theoretically predicted anisotropy of the effective hole masses is demonstrated. The study of the excitonic states in CuInSe2, CuInS2 and CuGaSe2 provides a deeper understanding of the electronic material properties which can facilitate further improvements in solar cell efficiencies.

Available in PDF, EPUB and Kindle. Book excerpt: Doped by isovalent or heterovalent foreign impurities, II–VI semiconductor compounds enable control of optical and electronic properties, making them ideal in detectors, solar cells, and other precise device applications. Quaternary alloys allow a simultaneous adjustment of band gap and lattice constant, increasing radiant efficiency at a wide range of wavelengths. Quaternary Alloys Based on II–VI Semiconductors consolidates data pertaining to diagrams of quaternary systems based on these semiconductor compounds. The book illustrates up-to-date experimental and theoretical information about phase relations based on II–VI semiconductor systems with four components. It critically evaluates many industrially significant systems presented in two-dimensional sections for the condensed phases. The author classifies all materials according to the periodic groups of their constituent atoms and additional components in the order of their group number. Each quaternary database description contains brief information on the diagram type, possible phase transformations and physical–chemical interactions of the components, thermodynamic characteristics, and methods for equilibrium investigation and sample preparation. Most of the phase diagrams are in their original form. For those with varying published data, the text includes several versions for comparison. This book provides invaluable data for technologists and researchers involved in developing and manufacturing II–VI semiconductors at industrial and national laboratories. It is also suitable for phase relations researchers, inorganic chemists, and semiconductor physicists as well as graduate students in materials science and engineering.

Download or read book Semiconductors written by O. Madelung and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the New Series of Landolt-Bomstein the eleven volumes III/17a···i and III/22a,b present data on the properties of semiconductors on more than 6 000 pages with tables and (about 10 000) figures. The aim of the Series "Data in Science and Technology" is to built a bridge between the libraries, where such comprehensive handbooks are situated, and the laboratory. The first volume of this series, published in 1991, contains data on the most important groups of semiconductors, the group IV elements and the III-V compounds. From the wealth of data in the tables and figures of the Landolt-Bornstein volumes III/17a and III/22a,b about 10% were condensed into this first volume. It seemed not appropriate to condense to the same extent all the other material of the remaining nine subvolumes into several further DST volumes. Instead of it all remaining data have been put into the present volume. To do this some severe restrictions became necessary. They are explained in the Introduction, and the reader is asked to read it before using this book. I would further like to focus the attention of the reader on chapter 8, where the bridge between this DST volume and the LB sources is built by cross-references between both books. I do hope that this volume meets the needs of the physical community as a quick reference to basic semiconductor data and an access to the larger data collections on this field of physics.
