Book Description
This second edition of the book presents spintronic properties of III–V nitride semiconductors. As wide bandgap III-nitride nanostructures are relatively new materials, the book pays particular attention to the difference between zinc-blende GaAs- and wurtzite GaN-based structures where the Rashba spin–orbit interaction plays a crucial role in voltage-controlled spin engineering. It also deals with topological insulators and discusses electrically driven zero-magnetic-field spin-splitting of surface electrons with respect to the specifics of electron-localized spin interaction and voltage-controlled ferromagnetism. It describes the recently identified zero-gap state—an anomalous quantum semimetal. The book comprises calculation of topological indexes in semiconductor and semimetal phases. It compares results that follow from the low-energy model and the Bernevig–Huges–Zhang model, which accounts for the full-Brillouin-zone electron spectrum. It also discusses the fractional quantization of Hall conductance and performs the direct calculation of Chern numbers for the inverted GaN/InN quantum well, determining topological properties by Chern number |C |=2. The book explores and actively discusses semiconductor spintronics and proposes various device implementations along the way. Although writings on this topic appear in the current literature, this book is focused on the materials science side of the question, providing a theoretical background for the most common concepts of spin-electron physics. It covers generic topics in spintronics without entering into device specifics since its aim is to give instructions to be used in solving problems of a general and specific nature. It is intended for graduate students and will serve as an introductory course in this specific field of solid state theory and applications.

Book Description
Semiconductor spintronics is expected to lead to a new generation of transistors, lasers and integrated magnetic sensors that can be used to create ultra-low power, high speed memory, logic and photonic devices. Useful spintronic devices will need materials with practical magnetic ordering temperatures and current research points to gallium and aluminium nitride magnetic superconductors as having great potential. This book details current research into the properties of III-nitride semiconductors and their usefulness in novel devices such as spin-polarized light emitters, spin field effect transistors, integrated sensors and high temperature electronics. Written by three leading researchers in nitride semiconductors, the book provides an excellent introduction to gallium nitride technology and will be of interest to all reseachers and industrial practitioners wishing to keep up to date with developments that may lead to the next generation of transistors, lasers and integrated magnetic sensors.

Book Description
The isolation of graphene in 2004 by two scientists at the University of Manchester—a breakthrough later recognised by the Nobel Prize for physics—revealed to the world a brand new ‘wonder material’ which had been ‘completely hidden from science’. Graphene, the world’s first two-dimensional material, promises huge opportunities for a range of sectors, from aerospace to energy to biomedical. But how can the UK be known for ‘Made in Britain’ as well as discovered in Britain? As an answer, this book explores how the Manchester model of innovation has evolved to not only support great science but also accelerate the adoption of graphene into real-world products and anchoring an innovation ecosystem in the place of UK discovery. This book features first-hand experience, case studies and interviews with key strategic players in the graphene story to illustrate how Manchester has built a unique model of collaboration with industry to create an ecosystem that features a supply chain of companies not only producing graphene material but also starting to disrupt the marketplace with new products and application as we approach the tipping point of commercialisation.

Book Description
This book presents the latest developments in semiconducting materials and devices, providing up-to-date information on the science, processes, and applications in the field. A wide range of topics are covered, including optoelectronic devices, metal–semiconductor junctions, heterojunctions, MISFETs, LEDs, semiconductor lasers, photodiodes, switching diodes, tunnel diodes, Gunn diodes, solar cells, varactor diodes, IMPATT diodes, and advanced semiconductors. Detailed attention is paid to advanced and futuristic materials. In addition, clear explanations are provided of, for example, electron theories, high-field effects, the Hall effect, transit-time effects, drift and diffusion, breakdown mechanisms, equilibrium and transient conditions, switching, and biasing. The book is designed to meet the needs of undergraduate engineering students and will also be very useful for postgraduate students; it will assist in preparation for examinations at colleges and universities and for other examinations in engineering. Practice questions are therefore presented in both essay and multiple choice format, and many solved examples and unsolved problems are included.
