Titelbeschreibung

This book presents both fundamental knowledge and latest achievements of this rapidly growing field in the last decade. It presents a complete and concise picture of the the state-of-the-art in the field, encompassing the most active international research groups in the world. Led by contributions from leading global research groups, the book discusses the functionalization of semiconductor surface. Dry organic reactions in vacuum and wet organic chemistry in solution are two major categories of strategies for functionalization that will be described. The growth of multilayer-molecular architectures on the formed organic monolayers will be documented. The immobilization of biomolecules such as DNA on organic layers chemically attached to semiconductor surfaces will be introduced. The patterning of complex structures of organic layers and metallic nanoclusters toward sensing techniques will be presented as well.

Discover how an emerging field is leading to a new generation of enhanced semiconductors Written by international leaders in the field, this book provides a complete and current review of the latest findings, practical applications, and active research in the organic functionalization of semiconductor surfaces. Readers will discover how the characteristics and properties of various organic functional groups when combined with inorganic semiconductor surfaces can lead to increasingly enhanced functional materials, including microchips and biosensors. Functionalization of Semiconductor Surfaces addresses all the important research questions in the field, starting with the basics and then advancing to more complex functionalization chemistry. The text begins with an introduction to the field and a discussion of essential experimental methods. Next, it presents: <ul> <li>Detailed descriptions of the structures of the relevant semiconductor surfaces</li> <li>Reviews of surface functionalization with progressively more complex organic functionalities</li> <li>Discussion of organic and biomaterial functionalization of semiconductor surfaces, including a chapter examining theoretical studies of these systems</li> <li>Both dry (vacuum) functionalization and wet chemical functionalization approaches</li> </ul> Clear illustrations of structures and mechanistic pathways enable readers to understand the underlying principles of organic functionalization of semiconductor surfaces and how these principles work in practice. Extensive bibliographies at the end of each chapter serve as a gateway to the field's growing body of literature. This book is invaluable for chemists, engineers, and students who are involved in investigations of the surface chemistry of semiconductors and organic functionalization of semiconductor surfaces. Moreover, the book sets the foundation for the development of the next generation of microelectronic computing, micro- and optoelectronic devices, microelectromechanical machines, three-dimensional memory chips, silicon-based nano sensors, and nano-patterned biomaterials.
