This book was released on 2011-12 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semiconductors, the major area of research in materials science, have offered solutions to several important technological problems and provided many devices for day to day applications. Development in novel semiconductor materials such as heterostructure systems and the ever-diminishing size of devices are producing an explosion of interest and activity in the field of semiconductor materials and devices. The characterization of epitaxial layers and their surfaces have benefited a lot from the enormous progress of micro and nanomechanical analysis techniques. In particular, the dramatic improvement of the structural quality of semiconductor materials results from the level of sophistication achieved with such analysis techniques. First of all, micromechanical technique is nondestructive and its sensitivity has been improved to such an extent that nowadays the epilayer analysis can be performed on layers with thicknesses ranging on the atomic scale. Thus, this book addresses some of the collective works on III-V semiconductors which could be to be extremely important from a technological point of view, i.e., for the surveillance of modern semiconductor processes.

Available in PDF, EPUB and Kindle. Book excerpt: Almost all the semiconductors of practical interest are the group-IV, III-V and II-VI semiconductors and the range of technical applications of such semiconductors is extremely wide. The purpose of this book is twofold: * to discuss the key properties of the group-IV, III-V and II-VI semiconductors * to systemize these properties from a solid-state physics aspect The majority of the text is devoted to the description of the lattice structural, thermal, elastic, lattice dynamic, electronic energy-band structural, optical and carrier transport properties of these semiconductors. Some corrective effects and related properties, such as piezoelectric, elastooptic and electrooptic properties, are also discussed. The book contains convenient tables summarizing the various material parameters and the definitions of important semiconductor properties. In addition, graphs are included in order to make the information more quantitative and intuitive. The book is intended not only for semiconductor device engineers, but also physicists and physical chemists, and particularly students specializing in the fields of semiconductor synthesis, crystal growth, semiconductor device physics and technology.

This book was released on 2013 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to obtain tunable properties with composition makes multi-ternary alloys extremely useful for a variety of applications in semiconductor devices and is of significant interest in experimental and theoretical research. This dissertation investigates the mechanical, electronic and optical properties of multi-ternary, i.e., binary, ternary and quaternary, semiconductor alloys using analytical methods and first-principles calculations. For the calculations of mechanical properties, existing models on the average shear modulus of III-V & II-VI binary semiconductors are revised. New expressions are developed for the average Young's modulus as well as the shear modulus and Young's modulus on (111) plane for these compounds. It is found that the proposed models provide a simple and accurate means for predicting the elastic constants of ternary semiconductors. The crystal structures, formation enthalpies and electronic properties of alloys, GaP[subscript X]Sb1−[subscript X], InP[subscript X]Sb1−[subscript X] and CdS[subscript X]Te1−[subscript X], are then investigated using first-principles calculations. These alloys are studied for various structures and compositions. Comparisons between GaP[subscript X] Sb1−[subscript X] and InP[subscript X] Sb1−[subscript X] are made. In the study of CdS[subscript X]Te1−[subscript X] system, negative bowing parameter of spin-orbit splitting is found in the ordered structure while positive value is found in disordered structure. This work also gives a recipe to calculate the properties of Y2 alloys in any degree of crystal ordering. For the partially ordered samples, the trends of the Y2 ordering induced changes in the crystal field splitting and band gap narrowing are explored and explained in terms of the lattice mismatch and band offset between the binary constituents. The Y2 ordering induced change in the spin-orbit splitting is found to be positive and small. Additionally, a model for the pressure dependence of the energy gap of group III-V & II-VI ternary semiconductor alloys is proposed. The trends in the pressure coefficients with respect to nearest neighbor distance and ionicity are discussed. Finally, the electronic and optical properties of Cu2ZnGeS4, Cu2ZnGeSe4 and Cu2ZnGeTe4 in KS and ST structures are studied. Band structure and optical spectra including the dielectric function, refractive index, absorption coefficient and reflectivity are determined. The critical points in the optical spectra are assigned to the interband transitions in accord with the calculated band structures. The trends of these properties with respect to crystal structures and VI (S, Se and Te) anion atoms are explored qualitatively.

Available in PDF, EPUB and Kindle. Book excerpt: The alloy system A1GaAs/GaAs is potentially of great importance for many high-speed electronics and optoelectronic devices, because the lattice parameter difference GaAs and A1GaAs is very small, which promises an insignificant concentration of undesirable interface states. Thanks to this prominent feature, a number of interesting properties and phenomena, such as high-mobility low-dimensional carrier gases, resonant tunnelling and fractional quantum Hall effect, have been found in the A1GaAs/GaAs heterostructure system. New devices, such as modulation-doped FETs, heterojunction bipolar transistors, resonant tunnelling transistors, quantum-well lasers, and other photonic and quantum-effect devices, have also been developed recently using this material system. These areas are recognized as not being the most interesting and active fields in semiconductor physics and device engineering.

Download or read book Heteroepitaxy of Semiconductors written by John E. Ayers and published by CRC Press. This book was released on 2018-10-08 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heteroepitaxy has evolved rapidly in recent years. With each new wave of material/substrate combinations, our understanding of how to control crystal growth becomes more refined. Most books on the subject focus on a specific material or material family, narrowly explaining the processes and techniques appropriate for each. Surveying the principles common to all types of semiconductor materials, Heteroepitaxy of Semiconductors: Theory, Growth, and Characterization is the first comprehensive, fundamental introduction to the field. This book reflects our current understanding of nucleation, growth modes, relaxation of strained layers, and dislocation dynamics without emphasizing any particular material. Following an overview of the properties of semiconductors, the author introduces the important heteroepitaxial growth methods and provides a survey of semiconductor crystal surfaces, their structures, and nucleation. With this foundation, the book provides in-depth descriptions of mismatched heteroepitaxy and lattice strain relaxation, various characterization tools used to monitor and evaluate the growth process, and finally, defect engineering approaches. Numerous examples highlight the concepts while extensive micrographs, schematics of experimental setups, and graphs illustrate the discussion. Serving as a solid starting point for this rapidly evolving area, Heteroepitaxy of Semiconductors: Theory, Growth, and Characterization makes the principles of heteroepitaxy easily accessible to anyone preparing to enter the field.
