Issues relating to the high-K gate dielectric are among the greatest challenges for the evolving International Technology Roadmap for Semiconductors (ITRS). More than just an historical overview, this book will assess previous and present approaches related to scaling the gate dielectric and their impact, along with the creative directions and forthcoming challenges that will define the future of gate dielectric scaling technology.

This book presents a theory for unconventional superconductivity driven by spin excitations. Using the Hubbard Hamiltonian and a self-consistent treatment of the spin excitations, the interplay between magnetism and superconductivity in various unconventional superconductors is discussed. In particular, the monograph applies this theory for Cooper-pairing due to the exchange of spin fluctuations to the case of singlet pairing in hole- and electron-doped high-Tc superconductors, and to triplet pairing in
Sr2RuO4. Within the framework of a generalized Eliashberg-like treatment,...

The 2008 Spring Meeting of the Arbeitskreis Festkorperphysik was held in Berlin, Germany, between February 24 and February 29, 2008 in conjunction with the 72nd Annual Meeting of the Deutsche Physikalische Gesellschaft. The 2008 meeting was the largest physics meeting in Europe and among the largest physics meetings in the world in 2008.

Quantum size effects are becoming increasingly important in microelectronics, as the dimensions of the structures shrink laterally towards 100 nm and vertically towards 10 nm. Advanced device concepts will exploit these effects for integrated circuits with novel or improved properties. Keeping in mind the trend towards systems on chip, this book deals with silicon-based quantum devices and focuses on room-temperature operation. The basic physical principles, materials, technological aspects, and fundamental device operation are discussed in an interdisciplinary manner. It is shown that...

This book presents written versions of selected invited lectures from the spring meeting of the Arbeitskreis Festkorperphysik of the Deutsche Physikalische Gesellschaft which was held from 27 to 31 March 2006 in Dresden, Germany. Many topical talks given at the numerous symposia are included. Most of these were organized collaboratively by several of the divisions of the Arbeitskreis. The book presents, to some extent, the status of the field of solid-state physics in 2006 not only in Germany but also internationally.

The 2007 Spring Meeting of the Arbeitskreis Festkorperphysik was held in Regensburg, Germany, between March 26 and March 30 2007 in conjunction with the 71st Annual Meeting of the Deutsche Physikalische Gesellschaft. This year's meeting was certainly one of the largest physics meetings in Europe.

The present volume 47 of the Advances in Solid State Physics contains the written version of a large number of the invited talks and gives an overview of the present status of solid state physics where low-dimensional systems such as quantum dots and quantum wires are dominating. The...

This is an overview of recording principles, materials aspects, and applications of rewritable optical storage. Elements of data recording, including mark formation, eraseability, direct overwrite strategies, data quality and data stability are explained and extensively discussed. Throughout the book, a mark formation model is described and used to back-up measurement results and support the discussed applications. High-speed and dual-layer recording are analyzed in depth, with proposals to achieve higher performance.

The 2nd edition emphasizes two areas not emphasized in the 1st edition: 1) high-temperature superconductor (HTS) magnets; 2) NMR (nuclear magnetic resonance) and MRI (magnetic resonance imaging) magnets.

Despite nearly 40 years of R and D on superconducting magnet technology, most areas, notably fusion and electric power applications, are still in the R and D stage. One exception is in the area of NMR and MRI. NMR magnets are very popular among chemists, biologists, genome scientists, and most of all, by drug manufacturers for drug discovery and development. MRI and NMR magnets...
