Modern electronics is being transformed as device size decreases to a size where the dimensions are significantly smaller than the constituent electron''s mean free path. In such systems the electron motion is strongly confined resulting in dramatic changes of behaviour compared to the bulk. This book introduces the physics and applications of transport in such mesoscopic and nanoscale electronic systems and devices. The behaviour of these novel devices is influenced by numerous effects not seen in bulk semiconductors, such as the Aharonov-Bohm Effect, disorder and localization, energy quantization, electron wave interference, spin splitting, tunnelling and the quantum hall effect to name a few. Including coverage of recent developments, and with a chapter on carbon-based nanoelectronics, this book will provide a good course text for advanced students or as a handy reference for researchers or those entering this interdisciplinary area.

Renewable energy sources are large but some are variable and intermittent. The wide-scale use of renewable energy sources for energy supply will require the adoption of ways to compensate for their variability. This book reviews the technical options looking at their pros and cons and how they might work together to support a reliable and sustainable energy system. Renewable energy use is expanding rapidly - it supplies nearly a quarter of global electricity at present and there are plans to expand that dramatically. In which case, the need for balancing measures to deal with the variability of some of the sources, will become vital. This is a rapidly advancing area of research and practice and Balancing Green Power offers an ideal introduction to the field. It follows on from David Elliott''s previous book, Renewables: A review of sustainable energy supply options.

The last few years have seen dramatic advances in the growth, fabrication and characterization of low-dimensional materials (such as graphene) and nanostructures (such as those formed from ultrathin films, wires, discs and other "dots"), formed either singly or in spatially periodic arrays. Most studies of these artificially engineered materials have been driven by their potential for device applications that involve smaller and smaller physical dimensions. In particular, the dynamical properties of these materials are of fundamental interest for the devices that involve high-frequency operation and/or switching. Consequently, the different excitations, vibrational, magnetic, optical, electronic, and so on, need to be understood from the perspective of how their properties are modified in finite structures especially on the nanometre length scale due to the presence of surfaces and interfaces. Recently, the patterning of nanoelements, into periodic and other arrays, has become a focus of intense activity, leading for example to photonic crystals and their analogues such as phononic and magnonic crystals where the control of the band gaps in the excitation spectrum is a basis for applications. The nonlinear properties of the excitations are increasingly a topic of interest, as well as the linear dynamics.

Renewable energy is a fast-expanding field, welcomed by many as part of the answer to climate change and energy security concerns; but can renewables deliver enough energy reliably and economically? Rapid expansion continues in the area of renewable energy, with wind capacity expected to double over the next five years and PV solar perhaps treble in the same period. There have been some dramatic projections of potential expansion longer term, with some studies now suggesting that renewables could supply all, or nearly all, electricity needs globally and perhaps also all energy needs by 2050. In this book, David Elliott conveys the sense of excitement that abounds in this new area of technological development not only reviewing the basic technological options and how renewable technologies are being implemented and used around the world, but also considers the problems, including local environmental impacts and the need to deal with the variability of some renewable energy sources. Dividing the renewable energy supply options into those based on mechanical power, heat and light it also looks at some related energy-conversion options, including fuel cells, heat pumps and cogeneration/combined heat and power. The author explores how these new sources can be integrated and used together with technologies for reducing energy waste and demand to replace conventional energy sources and ensure a balance of supply and demand. After reviewing the renewable energy options, the book then considers implementation and policy issues, including storage and grid balancing; aspects that will play a critical role in the creation of sustainable, clean and viable renewable energy solutions. This is not a textbook - there are plenty available - instead the book reviews what is happening across this field at this time of great change and rapid development. Supplemented with many case studies and links to information sources, this book will be essential reading for scientists, engineers, policymakers and anybody involved with, or interested in, the implementation of green and renewable energy technologies, and the environmental aspects of modern energy demands.
