A state-of-the-art description of metastability observed in chalcogenide alloys is presented with the accent on the underlying physics. A comparison is made between sulphur(selenium)-based chalcogenide glasses, where numerous photo-induced phenomena take place entirely within the amorphous phase, and tellurides where a reversible crystal-to-amorphous phase-change transformation is a major effect. Applications of metastability in devices optical memories and nonvolatile electronic phase-change random-access memories among others are discussed, including the latest trends. Background...

Since scaling of CMOS is reaching the nanometer area serious limitations enforce the introduction of novel materials, device architectures and device concepts. Multi-gate devices employing high-k gate dielectrics are considered as promising solution overcoming these scaling limitations of conventional planar bulk CMOS. Variation Aware Analog and Mixed-Signal Circuit Design in Emerging Multi-Gate CMOS Technologies provides a technology oriented assessment of analog and mixed-signal circuits in emerging high-k and multi-gate CMOS technologies.

This book presents highlighted results coming up from NanoCarbon2011, a Brazilian Carbon event. The topics cover the latest advances in Brazilian basic and applied research related to different carbon materials. The chapters address reviews ontheir fundamental and outstanding properties and describe various classes of new promising high-tech applications for carbon materials.

Topological insulators are insulating in the bulk, but process metallic states present around its boundary owing to the topological origin of the band structure. The metallic edge or surface states are immune to weak disorder or impurities, and robust against the deformation of the system geometry. This book, the first of its kind on topological insulators, presents a unified description of topological insulators from one to three dimensions based on the modified Dirac equation. A series of solutions of the bound states near the boundary are derived, and the existing conditions of these...
