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.

This book reviews the solid core of fundamental scientific knowledge on laser-stimulated surface chemistry that has accumulated over the past few years. It provides a useful overview for the student and interested non-expert as well as essential reference data (photodissociation cross sections, thermochemical constants, etc.) for the active researcher.

Laser Speckle and Applications in Optics focuses on developments in laser speckle techniques, with emphasis on the experimental aspect of phenomena and on applications in optics. These applications include interference with scattered light, optical processing of images, and studies of surface roughness as well as displacements and deformations of diffuse objects.
This book is comprised of 10 chapters and begins by reviewing the elements of diffraction theory and the properties of speckle in the image of a diffuse object. The discussion then turns to speckle in the near field and interferometry with diffuse light, along with experiments in which interference patterns are produced from photographically superimposed laterally shifted speckle patterns. The following chapters consider optical processing of images modulated by speckle; deformations and displacements of diffuse objects; speckle applications in astronomy; and surface roughness measurements. The final chapter looks at the use of laser speckle to study transparent objects; the average shape of diffuse surfaces; the transfer functions and aberrations of optical systems; and the movement of diffuse objects.
This monograph will be of value to physicists and researchers as well as those interested in lasers and optics.

Laser spectroscopy is a valuable tool for sensing and chemical analysis. Developments in lasers, detectors and mathematical analytical tools have led to improvements in the sensitivity and selectivity of spectroscopic techniques and extended their fields of application. Laser Spectroscopy for Sensing examines these advances and how laser spectroscopy can be used in a diverse range of industrial, medical, and environmental applications.

Part one reviews basic concepts of atomic and molecular processes and presents the fundamentals of laser technology for controlling the spectral and temporal aspects of laser excitation. In addition, it explains the selectivity, sensitivity, and stability of the measurements, the construction of databases, and the automation of data analysis by machine learning. Part two explores laser spectroscopy techniques, including cavity-based absorption spectroscopy and the use of photo-acoustic spectroscopy to acquire absorption spectra of gases and condensed media. These chapters discuss imaging methods using laser-induced fluorescence and phosphorescence spectroscopies before focusing on light detection and ranging, photothermal spectroscopy and terahertz spectroscopy. Part three covers a variety of applications of these techniques, particularly the detection of chemical, biological, and explosive threats, as well as their use in medicine and forensic science. Finally, the book examines spectroscopic analysis of industrial materials and their applications in nuclear research and industry.

The text provides readers with a broad overview of the techniques and applications of laser spectroscopy for sensing. It is of great interest to laser scientists and engineers, as well as professionals using lasers for medical applications, environmental applications, military applications, and material processing.

Left-handedness has been connected to many different conditions, traits, and abilities.  This is especially true for pathological syndromes, such as schizophrenia, along with learning disabilities and autism.  The published research on handedness is vast and frequently contradictory, often raising more questions than providing answers.  Questions such as:

• Is handedness genetic?
• Can handedness be changed?
• Are there consequences to training someone to switch handedness?
• Are there positive traits associated with left-handedness like creativity?
• Are there negative traits associated with left-handedness like trouble reading maps?
• Is it abnormal to do some things right-handed and other things left-handed?
• Are the brains of left-handers different from the brains of right-handers?

Laterality: Exploring the Enigma of Left-Handedness examines the research conducted over the past 50 years with special emphasis on twenty-first century research on handedness and translates this literature into an accessible and readable form.  Each chapter is based on a question or questions covering diverse topics such as genetic and biological origins of handedness, familial and hormonal influences on handedness, and the effects of a majority right-handed world on the behaviors of left-handers.

• Summarizes scientific research on laterality
• Separates fact from fiction in common beliefs about laterality
• Includes illustrative interviews with left-handers

Most of the coral reefs of the American continent: the Brazilian waters, the Caribbean Sea and the eastern Pacific Ocean are in Latin American countries, the subject of this book. For the first time, information on coral reefs of such a vast region is mined from reports, obscure journals, university thesis and scientific journals, summarized and presented in a way both accessible and informative for the interested reader as well as for the coral reef expert. The chapters of the book, divided by country and ocean, were written by either scientists from the countries or by those that know the area well. Reefs not documented in the past are described in detail here, including location maps. The natural and anthropogenic impacts affecting the reefs are presented, as well as sections on management, conservation and legislation in each country. Nineteen chapters, plus an introduction, present information of coral reefs from Brazil to Mexico, and from Chile to Cuba.
