Carbon (C) and Silicon Germanium (SiGe) work like a magic sauce. At least in small concentrations, they make everything taste better. It is remarkable enough that SiGe, a new material, and the heterobipolar transistor, a new device, appear on the brink of impacting the exploding wireless market. The addition of C to SiGe, albeit in small concentrations, looks to have breakthrough potential. Here, at last, is proof that materials science can put a rocket booster on the silicon-mind, the silicon transistor. Scientific excitement arises, as always, from the new possibilities a multicomponent materials system offers. Bandgaps can be changed, strains can be tuned, and properties can be tailored. This is catnip to the materials scientist. The wide array of techniques applied here to the SiGeC system bear testimony to the ingenious approaches now available for mastering the complexities of new materials

This five-volume handbook focuses on processing techniques, characterization methods, and physical properties of thin films (thin layers of insulating, conducting, or semiconductor material). The editor has composed five separate, thematic volumes on thin films of metals, semimetals, glasses, ceramics, alloys, organics, diamonds, graphites, porous materials, noncrystalline solids, supramolecules, polymers, copolymers, biopolymers, composites, blends, activated carbons, intermetallics, chalcogenides, dyes, pigments, nanostructured materials, biomaterials, inorganic/polymer composites, organoceramics, metallocenes, disordered systems, liquid crystals, quasicrystals, and layered structures. Thin films is a field of the utmost importance in today's materials science, electrical engineering and applied solid state physics; with both research and industrial applications in microelectronics, computer manufacturing, and physical devices. Advanced, high-performance computers, high-definition TV, digital camcorders, sensitive broadband imaging systems, flat-panel displays, robotic systems, and medical electronics and diagnostics are but a few examples of miniaturized device technologies that depend the utilization of thin film materials. The Handbook of Thin Films Materials is a comprehensive reference focusing on processing techniques, characterization methods, and physical properties of these thin film materials.

In recent years, the development of powerful epitaxial growth techniques such as molecular beam epitaxy (MBE), ultra-high vacuum chemical vapour deposition (UHVCVD) and other low temperature epitaxy techniques have given rise to a new area of research of bandgap engineering in silicon based materials. This development has paved the way for heterojunction bipolar and field effect transistors, as well as for novel quantum devices. This title provides a comprehensive introduction to silicon heterostructures, including growth and characterization of materials and descriptions of new heterostructure devices, making it a useful reference for postgraduate students, researchers and scientists.

Despite the vast knowledge accumulated on silicon, germanium, and their alloys, these materials still demand research, eminently in view of the improvement of knowledge on silicon–germanium alloys and the potentialities of silicon as a substrate for high-efficiency solar cells and for compound semiconductors and the ongoing development of nanodevices based on nanowires and nanodots. Silicon, Germanium, and Their Alloys: Growth, Defects, Impurities, and Nanocrystals covers the entire spectrum of R&D activities in silicon, germanium, and their alloys, presenting the latest achievements in the field of crystal growth, point defects, extended defects, and impurities of silicon and germanium nanocrystals. World-recognized experts are the authors of the book’s chapters, which span bulk, thin film, and nanostructured materials growth and characterization problems, theoretical modeling, crystal defects, diffusion, and issues of key applicative value, including chemical etching as a defect delineation technique, the spectroscopic analysis of impurities, and the use of devices as tools for the measurement of materials quality.

Ever since the work of W.E. Spear and P.G. LeComber had proved that an amorphous semiconductor could indeed also be substitutionally doped, research in the respective field has seen an nearly unprecedented development. The role of hydrogen in atomic and electronic structure as well as in the doping mechanism remains an outstanding problem addressed both to theoreticians and experimentalists, and a highly interesting challenge both to the scientist as well as the engineer.
