Surfaces and interfaces play an increasingly important role in today's solid state devices. In this book the reader is introduced, in a didactic manner, to the essential theoretical aspects of the atomic and electronic structure of surfaces and interfaces. The book does not pretend to give a complete overview of contemporary problems and methods. Instead, the authors strive to provide simple but qualitatively useful arguments that apply to a wide variety of cases. The emphasis of the book is on semiconductor surfaces and interfaces but it also includes a thorough treatment of transition metals, a general discussion of phonon dispersion curves, and examples of large computational calculations. The exercises accompanying every chapter will be of great benefit to the student.
This book is about friendships in public settings today. Wilkinson examines friendships in the public settings of neighbourhoods, civil society and at work. Identifying the unique relevance which public friendships have to contemporary social problems, the chapters cover a range of topics, including work-life balance, women’s ‘double burden’ and their leisure deficit, and contemporary neighbouring initiatives. Wilkinson shows how ‘friendship time’ at work provides solutions to new social problems including privacy: with the modern workplace being hyper-public and emphasizing visibility, monitoring and 24/7 availability, friendship’s combination of voluntarism and trust enable a private refuge even in an open-plan office. The book also explores the way in which friendships in public settings like work and neighbourhood provide community to those in society who are more likely to be excluded from private familial intimacy. The Public Life of Friendship will be of interest to students and scholars across a range of social science disciplines with an interest in friendship and the sociology of personal life.
Provides the theoretical background needed by physicists, engineers and students to simulate nano-devices, semiconductor quantum dots and molecular devices. It presents in a unified way the theoretical concepts, the more recent semi-empirical and ab initio methods, and their application to experiments. The topics include quantum confinement, dielectric and optical properties, non-radiative processes, defects and impurities, and quantum transport. This guidebook not only provides newcomers with an accessible overview (requiring only basic knowledge of quantum mechanics and solid-state physics) but also provides active researchers with practical simulation tools.
The contributors to this topical volume explore the role of family support in promoting the welfare of children and their families. The book integrates concepts and experiences from an international perspective, different levels of analysis (society, community and family) and different loci of intervention.
Silicon, the leading material in microelectronics during the last four decades, also promises to be the key material in the future. Despite many claims that silicon technology has reached fundamental limits, the performance of silicon microelectronics continues to improve steadily. The same holds for almost all the applications for which Si was considered to be unsuitable. The main exception to this positive trend is the silicon laser, which has not been demonstrated to date. The main reason for this comes from a fundamental limitation related to the indirect nature of the Si band-gap. In the recent past, many different approaches have been taken to achieve this goal: dislocated silicon, extremely pure silicon, silicon nanocrystals, porous silicon, Er doped Si-Ge, SiGe alloys and multiquantum wells, SiGe quantum dots, SiGe quantum cascade structures, shallow impurity centers in silicon and Er doped silicon. All of these are abundantly illustrated in the present book.
The Encyclopedia of Community is a major four volume reference work that seeks to define one of the most widely researched topics in the behavioural and social sciences. Community itself is a concept, an experience, and a central part of being human. This pioneering major reference work seeks to provide the necessary definitions of community far beyond the traditional views.
Feeling Hurt in Close Relationships presents a synthesis of cutting-edge research and theory on hurt. Being hurt is an inevitable part of close relationships. What varies from relationship to relationship is not whether partners hurt each other, but how their relationship is affected by hurtful episodes. Given the potential influence of hurt feelings on people's interpersonal relationships, it is not surprising that scholars have begun to study the antecedents, processes, and outcomes associated with hurt. This collection integrates the various issues addressed by researchers, theorists, and practitioners who study the causes of hurt feelings, the interpersonal events associated with hurt, and the ways people respond to hurting and being hurt by others. To capture the breadth and depth of the literature in this area, the work of scholars from a variety of disciplines – including social psychology, communication, sociology, and family studies – is highlighted.
