The availability of various novel materials, such as semiconductors, tailor-made polymers and ceramics, has revolutionized information processing and transmission. Since the early fifties, semiconductors have formed the backbone of different information age technologies.The fabrication of state-of-the-art semiconducting devices requires either substrates or composite structures consisting of thin epitaxial layers. Over the years, great strides have been made both in growing bulk crystals and in controlled deposition of thin homo- and hetero-epitaxial layers. Understanding of the deformation behaviour of semiconductors has facilitated the growth of high-quality crystals. Heterostructures consisting of extremely thin layers and chemically and structurally sharp interfaces can be deposited. To tailor bandgaps and electronic properties, silicon-germanium/silicon heterojunctions, mixed III-V epitaxial layers that are ordered and phase separated and quantum-well structures have been grown. Also, to improve the optical, electrical and structural quality of as-grown bulk and thin film materials, a variety of interdisciplinary studies have been carried out that has resulted in a number of sophisticated techniques to evaluate semiconductors.In this volume, scientific issues relevant to these topics and others are discussed in detail. The coverage is in-depth and broad. The resulting volume should serve as a major reference source for education and research on semiconducting materials.A schematic diagram of the essential stages in the fabrication of a quantum wire: (a) substrate of material A after 0.5 ML deposition of ...
