Laser Annealing of Semiconductors deals with the materials science of surfaces that have been subjected to ultrafast heating by intense laser or electron beams. This book is organized into 13 chapters that specifically tackle transient annealing of compound semiconductors. After briefly dealing with an overview of laser annealing, this book goes on discussing the concepts of solidification and crystallization pertinent to the field. These topics are followed by discussions on the main mechanisms of interaction of photon and electron beams with condensed matter; the calculation of thermophysical properties of crystalline materials; and high-speed crystal growth by laser annealing of ion-implanted silicon. The subsequent chapters describe the microstructural and topographical properties of annealed semiconductor layers and the epitaxy of ion-implanted silicon irradiated with a laser or electron beam single pulse. This text also explores the electronic and surface properties and the continuous-wave beam processing of semiconductors. The concluding chapters cover various reactions in metal-semiconductor systems, such as fast and laser-induced melting, solidification, mixing, and quenching. Laser-induced interactions in metal-semiconductor systems and the factors involved in control of the heat treatment process are also discussed in these chapters. Materials scientists and researchers and device engineers will find this book invaluable.

The work on annealing of displacement damage, dissolution of boron precipitates, and the broadening of dopant profiles in semiconductors after treating with ruby and dye laser pulses is reviewed in order to provide convincing evidence for the melting phenomenon and illustrate the mechanism associated with laser annealing. The nature of the solid-liquid interface and the interface instability during rapid solidification is considered in detail. It is shown that solute concentrations after pulsed laser annealing can far exceed retrograde maxima values. However, there is a critical solute concentration above which a planar solid-liquid interface becomes unstable and breaks into a cellular structure. The solute concentrations and cell sizes associated with this instability are calculated using a perturbation theory, and compared with experimental results.

Semiconductors Probed by Ultrafast Laser Spectroscopy, Volume II discusses the use of ultrafast laser spectroscopy in studying fast physics in semiconductors. It reviews progress on the experimental and theoretical understanding of ultrafast events that occur on a picosecond and nanosecond time scale. This volume discusses electronic relaxation in amorphous semiconductors and the physical mechanisms during and after the interaction of an intense laser pulse with a semiconductor. It also covers the relaxation of carriers in semiconductors; transient optical pulse propagation; and methods of time-resolved spectroscopy. Scientists, engineers, and graduate students will find this book invaluable.

This book describes advanced epitaxial growth and self-aligned processing techniques for the fabrication of III-V semiconductor devices such as heterojunction bipolar transistors and high electron mobility transistors. It is the first book to describe the use of carbon-doping and low damage dry etching techniques that have proved indispensable in making reliable, high performance devices. These devices are used in many applications such as cordless telephones and high speed lightwave communication systems.

Lasers are becoming increasingly important in surface science, both for the diagnostic evaluation and the processing of surfaces, for example, higher harmonic generation for diagnosis and the widespread use of laser surface microstructuring and annealing for processing. The physics behind such applications might be described in some cases by simple heating and melting processes, but can also include much more complex phenomena such as plasma generation or elementary collective surface excitations. Laser Applications in Surface Science and Technology provides an overview of the different techniques, discusses the principles behind them and gives a concise description of laser-induced and laser-detected processes on surfaces. Recent developments in the field such as nonlinear surface spectroscopies and the interactions of ultrashort pulses with materials, are also introduced. Invaluable reading for postgraduate students and research scientists across a wide range of disciplines including: physics, chemistry, electronic engineering and materials science.

The Proceedings of the 17th International Conference on the Physics of Semiconductors are contained in this volume. A record 1050 scientists from 40 countries participated in the Conference which was held in San Francisco August 6·1 0, 1984. The Conference was organized by the ICPS Committee and sponsored by the International Union of Pure and Applied Physics and other professional, government, and industrial organizations listed on the following pages. Papers representing progress in all aspects of semiconductor physics were presented. Far more abstracts (765) than could be presented in a five-day meeting were considered by the International Program Committee. A total of 350 papers, consisting of 5 plenary, 35 invited, and 310 contributed, were presented at the Conference in either oral or poster sessions. All but a few of the papers were submitted and have been included in these Proceedings. An interesting shift in subject matter, in comparison with earlier Conferences, is manifested by the large number of papers on surfaces, interfaces, and quantum wells. To facilitate the use of the Proceedings in finding closely related papers among the sometimes relatively large number of contributions within a main subject area, we chose not to arrange the papers strictly according to the Conference schedule. We have organized the book, as can be seen from the Contents, into specific subcategories and subdivisions within each major category. Plenary and invited papers have been placed together with the appropriate contributed papers.

This volume is a collection of 96 papers presented at the above Conference. The scope of the work includes optical and electrical methods as well as techniques for structural and compositional characterization. The contributed papers report on topics such as X-ray diffraction, TEM, depth profiling, photoluminescence, Raman scattering and various electrical methods. Of particular interest are combinations of different techniques providing complementary information. The compound semiconductors reviewed belong mainly to the III-V and III-VI families. The papers in this volume will provide a useful reference on the implications of new technologies in the characterization of compound semiconductors.

The thermal processing of materials ranges from few fem to seconds by Swift Heavy Ion Implantation to about one second using advanced Rapid Thermal Annealing. This book offers after an historical excursus selected contributions on fundamental and applied aspects of thermal processing of classical elemental semiconductors and other advanced materials including nanostructures with novel optoelectronic, magnetic, and superconducting properties. Special emphasis is given on the diffusion and segregation of impurity atoms during thermal treatment. A broad range of examples describes the solid phase and/or liquid phase processing of elemental and compound semiconductors, dielectric composites and organic materials.
