Communication and information systems are subject to rapid and highly so phisticated changes. Currently semiconductor heterostructure devices, such as Heterojunction Bipolar Transistors (HBTs) and High Electron Mobility Transis tors (HEMTs), are among the fastest and most advanced high-frequency devices. They satisfy the requirements for low power consumption, medium integration, low cost in large quantities, and high-speed operation capabilities in circuits. In the very high-frequency range, cut-off frequencies up to 500 GHz [557] have been reported on the device level. HEMTs and HBTs are very suitable for high efficiency power amplifiers at 900 MHz as well as for data rates higher than 100 Gbitfs for long-range communication and thus cover a broad range of appli cations. To cope with explosive development costs and the competition of today's semicon ductor industry, Technology Computer-Aided Design (TCAD) methodologies are used extensively in development and production. As of 2003, III-V semiconductor HEMT and HBT micrometer and millimeter-wave integrated circuits (MICs and MMICs) are available on six-inch GaAs wafers. SiGe HBT circuits, as part of the CMOS technology on eight-inch wafers, are in volume production. Simulation tools for technology, devices, and circuits reduce expensive technological efforts. This book focuses on the application of simulation software to heterostructure devices with respect to industrial applications. In particular, a detailed discussion of physical modeling for a great variety of materials is presented.

This thesis presents an in-depth exploration of imperfections that can be found in self-catalysed III-V semiconductor nanowires. By utilising advanced electron microscopy techniques, the interface sharpness and defects at the atomic and macroscopic scale are analysed. It is found that a surprising variety and quantity of defect structures can exist in nanowire systems, and that they can in fact host some never-before-seen defect configurations. To probe how these defects are formed, conditions during nanowire growth can be emulated inside the microscope using the latest generation of in-situ heating holder. This allowed the examination of defect formation, dynamics, and removal, revealing that many of the defects can in fact be eliminated. This information is critical for attaining perfect nanowire growth. The author presents annealing strategies to improve crystal quality, and therefore device performance.

Characterization of Semiconductor Heterostructures and Nanostructures is structured so that each chapter is devoted to a specific characterization technique used in the understanding of the properties (structural, physical, chemical, electrical etc..) of semiconductor quantum wells and superlattices. An additional chapter is devoted to ab initio modeling. The book has two basic aims. The first is educational, providing the basic concepts of each of the selected techniques with an approach understandable by advanced students in Physics, Chemistry, Material Science, Engineering, Nanotechnology. The second aim is to provide a selected set of examples from the recent literature of the TOP results obtained with the specific technique in understanding the properties of semiconductor heterostructures and nanostructures. Each chapter has this double structure: the first part devoted to explain the basic concepts, and the second to the discussion of the most peculiar and innovative examples. The topic of quantum wells, wires and dots should be seen as a pretext of applying top level characterization techniques in understanding the structural, electronic etc properties of matter at the nanometer (and even sub-nanometer) scale. In this respect it is an essential reference in the much broader, and extremely hot, field of Nanotechnology. Comprehensive collection of the most powerful characterization techniques for semiconductors heterostructures and nanostructures Most of the chapters are authored by scientists that are world-wide among the top-ten in publication ranking of the specific field Each chapter starts with a didactic introduction on the technique The second part of each chapters deals with a selection of top examples highlighting the power of the specific technique to analyse the properties of semiconductors heterostructures and nanostructures

This volume constitutes the proceedings of the IUTAM Symposium on Surface Effects in the Mechanics of Nanomaterials and Heterostructures, held in Beijing, 8-12 August, 2010. The symposium brought together the most active scientists working in this area from the fields of solid mechanics, composites, physics, and materials science and summarized the state-of-the-art research results with a view to advancing the frontiers of mechanics and materials physics. Nanomaterials and heterostructures have a large fraction of their atoms at surfaces and interfaces. These atoms see a different environment to those in the interior and can have a substantial effect on the overall mechanical and physical behaviour of a material. The last decade has witnessed a growing interest in the study of surfaces and how the surface behaviour couples with that of the bulk to determine the overall system response. The papers in this proceedings cover: extension of continuum mechanics and thermodynamics to the nano-scale; multiscale simulations; surface effects in monolithic nano-scale elements and nanostructures; mechanical and physical properties of nanomaterials and heterostructures; self-assembly, etc. The surface stress effect is inherently a multidisciplinary and fertile field; the Symposium truly reflects these features. This IUTAM Symposium was also dedicated to Professor Bhushan L Karihaloo of Cardiff University on his impending retirement, in recognition of his contributions to the fields of solid mechanics and nanomechanics, and to IUTAM activities in general.

The Workshop Heterostructure Epitaxy and Devices HEAD'97 was held from October 12 to 16, 1997 at Smolenice Castle, the House of Scientists of the Slovak Academy of Sciences and was co-organized by the Institute of Electrical Engineering, Slovak Academy of Sciences, Bratislava and the Institute of Thin Film and Ion Technology, Research Centre, liilich. It was the third in a series of workshops devoted to topics related to heterostructure epitaxy and devices and the second included into the category of Advanced Research Workshops (ARW) under sponsorship of the NATO. More than 70 participants from 15 countries attended (Austria, Belarus, Belgium, Czech Republic, Finland, Germany, Greece, Hungary, Italy, Poland, Russia, Slovakia, Ukraine, the United Kingdom and the USA). Novel microelectronic and optoelectronic devices are based on semiconductor heterostructures. The goal of the ARW HEAD'97 was to discuss various questions related to the use of new materials (e.g. compound semiconductors based on high band-gap nitrides and low band-gap antimonides) and new procedures (low-temperature epitaxial growth), as well as new principles (nanostructures, quantum wires and dots, etc.) aimed at realizing high-performance heterostructure based electronic devices. Almost 70 papers (invited and contributed oral presentations as well as posters) were presented at the ARW HEAD'97 and the main part of them is included into these Proceedings.

This book is devoted to the rapidly developing field of oxide thin-films and heterostructures. Oxide materials combined with atomic-scale precision in a heterostructure exhibit an abundance of macroscopic physical properties involving the strong coupling between the electronic, spin, and structural degrees of freedom, and the interplay between magnetism, ferroelectricity, and conductivity. Recent advances in thin-film deposition and characterization techniques made possible the experimental realization of such oxide heterostructures, promising novel functionalities and device concepts. The book consists of chapters on some of the key innovations in the field over recent years, including strongly correlated oxide heterostructures, magnetoelectric coupling and multiferroic materials, thermoelectric phenomena, and two-dimensional electron gases at oxide interfaces. The book covers the core principles, describes experimental approaches to fabricate and characterize oxide heterostructures, demonstrates new functional properties of these materials, and provides an overview of novel applications.
